Old Unicode normalization API.

This API has been replaced by the Normalizer2 class and is only available for backward compatibility. This class simply delegates to the Normalizer2 class. There are two exceptions: The new API does not provide a replacement for QuickCheckResult and compare().

normalize transforms Unicode text into an equivalent composed or decomposed form, allowing for easier sorting and searching of text. normalize supports the standard normalization forms described in Unicode Standard Annex #15 — Unicode Normalization Forms.

Characters with accents or other adornments can be encoded in several different ways in Unicode. For example, take the character A-acute. In Unicode, this can be encoded as a single character (the "composed" form):

      00C1    LATIN CAPITAL LETTER A WITH ACUTE
 

or as two separate characters (the "decomposed" form):

      0041    LATIN CAPITAL LETTER A
      0301    COMBINING ACUTE ACCENT
 

To a user of your program, however, both of these sequences should be treated as the same "user-level" character "A with acute accent". When you are searching or comparing text, you must ensure that these two sequences are treated equivalently. In addition, you must handle characters with more than one accent. Sometimes the order of a character's combining accents is significant, while in other cases accent sequences in different orders are really equivalent.

Similarly, the string "ffi" can be encoded as three separate letters:

      0066    LATIN SMALL LETTER F
      0066    LATIN SMALL LETTER F
      0069    LATIN SMALL LETTER I
 

or as the single character

      FB03    LATIN SMALL LIGATURE FFI
 

The ffi ligature is not a distinct semantic character, and strictly speaking it shouldn't be in Unicode at all, but it was included for compatibility with existing character sets that already provided it. The Unicode standard identifies such characters by giving them "compatibility" decompositions into the corresponding semantic characters. When sorting and searching, you will often want to use these mappings.

normalize helps solve these problems by transforming text into the canonical composed and decomposed forms as shown in the first example above. In addition, you can have it perform compatibility decompositions so that you can treat compatibility characters the same as their equivalents. Finally, normalize rearranges accents into the proper canonical order, so that you do not have to worry about accent rearrangement on your own.

Form FCD, "Fast C or D", is also designed for collation. It allows to work on strings that are not necessarily normalized with an algorithm (like in collation) that works under "canonical closure", i.e., it treats precomposed characters and their decomposed equivalents the same.

It is not a normalization form because it does not provide for uniqueness of representation. Multiple strings may be canonically equivalent (their NFDs are identical) and may all conform to FCD without being identical themselves.

The form is defined such that the "raw decomposition", the recursive canonical decomposition of each character, results in a string that is canonically ordered. This means that precomposed characters are allowed for as long as their decompositions do not need canonical reordering.

Its advantage for a process like collation is that all NFD and most NFC texts - and many unnormalized texts - already conform to FCD and do not need to be normalized (NFD) for such a process. The FCD quick check will return YES for most strings in practice.

normalize(FCD) may be implemented with NFD.

For more details on FCD see Unicode Technical Note #5 (Canonical Equivalence in Applications): http://www.unicode.org/notes/tn5/#FCD

ICU collation performs either NFD or FCD normalization automatically if normalization is turned on for the collator object. Beyond collation and string search, normalized strings may be useful for string equivalence comparisons, transliteration/transcription, unique representations, etc.

The W3C generally recommends to exchange texts in NFC. Note also that most legacy character encodings use only precomposed forms and often do not encode any combining marks by themselves. For conversion to such character encodings the Unicode text needs to be normalized to NFC. For more usage examples, see the Unicode Standard Annex.

Note: The Normalizer class also provides API for iterative normalization. While the setIndex() and getIndex() refer to indices in the underlying Unicode input text, the next() and previous() methods iterate through characters in the normalized output. This means that there is not necessarily a one-to-one correspondence between characters returned by next() and previous() and the indices passed to and returned from setIndex() and getIndex(). It is for this reason that Normalizer does not implement the CharacterIterator interface.

Status:

Stable ICU 2.8.

NO_OP

@Deprecated
public static final Normalizer.Mode NO_OP

Deprecated. ICU 2.8. Use Nomalizer.NONE

Null operation for use with the constructors and the static normalize method. This value tells the Normalizer to do nothing but return unprocessed characters from the underlying String or CharacterIterator. If you have code which requires raw text at some times and normalized text at others, you can use NO_OP for the cases where you want raw text, rather than having a separate code path that bypasses Normalizer altogether.

setMode(com.ibm.icu.text.Normalizer.Mode), NONE

COMPOSE

@Deprecated
public static final Normalizer.Mode COMPOSE

Deprecated. ICU 2.8. Use Normalier.NFC

Canonical decomposition followed by canonical composition. Used with the constructors and the static normalize method to determine the operation to be performed.

If all optional features (e.g. IGNORE_HANGUL) are turned off, this operation produces output that is in Unicode Canonical Form C.

See Also:

setMode(com.ibm.icu.text.Normalizer.Mode), NFC

COMPOSE_COMPAT

@Deprecated
public static final Normalizer.Mode COMPOSE_COMPAT

Deprecated. ICU 2.8. Use Normalizer.NFKC

If all optional features (e.g. IGNORE_HANGUL) are turned off, this operation produces output that is in Unicode Canonical Form KC.

See Also:

setMode(com.ibm.icu.text.Normalizer.Mode), NFKC

DECOMP

@Deprecated
public static final Normalizer.Mode DECOMP

Deprecated. ICU 2.8. Use Normalizer.NFD

Canonical decomposition. This value is passed to the constructors and the static normalize method to determine the operation to be performed.

See Also:

setMode(com.ibm.icu.text.Normalizer.Mode), NFD

IGNORE_HANGUL

@Deprecated
public static final int IGNORE_HANGUL

Deprecated. ICU 2.8. This option is no longer supported.

Option to disable Hangul/Jamo composition and decomposition. This option applies to Korean text, which can be represented either in the Jamo alphabet or in Hangul characters, which are really just two or three Jamo combined into one visual glyph. Since Jamo takes up more storage space than Hangul, applications that process only Hangul text may wish to turn this option on when decomposing text.

The Unicode standard treats Hangul to Jamo conversion as a canonical decomposition, so this option must be turned off if you wish to transform strings into one of the standard Unicode Normalization Forms.

@Deprecated
public static final int COMPARE_NORM_OPTIONS_SHIFT

Deprecated. ICU 56 Use Normalizer2 instead.

Lowest-order bit number of compare() options bits corresponding to normalization options bits.

Parameters:

src - The input array of characters to be checked to see if it is normalized

start - The strart index in the source

limit - The limit index in the source

mode - the normalization mode

options - Options for use with exclusion set and tailored Normalization The only option that is currently recognized is UNICODE_3_2

                          int options)

Compare two strings for canonical equivalence. Further options include case-insensitive comparison and code point order (as opposed to code unit order). Canonical equivalence between two strings is defined as their normalized forms (NFD or NFC) being identical. This function compares strings incrementally instead of normalizing (and optionally case-folding) both strings entirely, improving performance significantly. Bulk normalization is only necessary if the strings do not fulfill the FCD conditions. Only in this case, and only if the strings are relatively long, is memory allocated temporarily. For FCD strings and short non-FCD strings there is no memory allocation. Semantically, this is equivalent to strcmp[CodePointOrder](foldCase(NFD(s1)), foldCase(NFD(s2))) where code point order and foldCase are all optional.

Parameters:

s1 - First source character array.

s1Start - start index of source

s1Limit - limit of the source

s2 - Second source character array.

s2Start - start index of the source

s2Limit - limit of the source

options - A bit set of options: - FOLD_CASE_DEFAULT or 0 is used for default options: Case-sensitive comparison in code unit order, and the input strings are quick-checked for FCD. - INPUT_IS_FCD Set if the caller knows that both s1 and s2 fulfill the FCD conditions.If not set, the function will quickCheck for FCD and normalize if necessary. - COMPARE_CODE_POINT_ORDER Set to choose code point order instead of code unit order - COMPARE_IGNORE_CASE Set to compare strings case-insensitively using case folding, instead of case-sensitively. If set, then the following case folding options are used.

Returns:

<0 or 0 or >0 as usual for string comparisons

Concatenate normalized strings, making sure that the result is normalized as well. If both the left and the right strings are in the normalization form according to "mode", then the result will be dest=normalize(left+right, mode) With the input strings already being normalized, this function will use next() and previous() to find the adjacent end pieces of the input strings. Only the concatenation of these end pieces will be normalized and then concatenated with the remaining parts of the input strings. It is allowed to have dest==left to avoid copying the entire left string.

Parameters:

left - Left source array, may be same as dest.

leftStart - start in the left array.

leftLimit - limit in the left array (==length)

right - Right source array.

rightStart - start in the right array.

rightLimit - limit in the right array (==length)

dest - The output buffer; can be null if destStart==destLimit==0 for pure preflighting.

destStart - start in the destination array

destLimit - limit in the destination array (==length)

mode - The normalization mode.

options - The normalization options, ORed together (0 for no options).

Returns:

Length of output (number of chars) when successful or IndexOutOfBoundsException

Throws:

IndexOutOfBoundsException - whose message has the string representation of destination capacity required.

setIndexOnly

@Deprecated
public void setIndexOnly(int index)

Deprecated. ICU 56

Set the iteration position in the input text that is being normalized, without any immediate normalization. After setIndexOnly(), getIndex() will return the same index that is specified here.

Parameters:

index - the desired index in the input text.

setIndex

@Deprecated
public int setIndex(int index)

Deprecated. ICU 3.2

Set the iteration position in the input text that is being normalized and return the first normalized character at that position.

Note: This method sets the position in the input text, while next() and previous() iterate through characters in the normalized output. This means that there is not necessarily a one-to-one correspondence between characters returned by next and previous and the indices passed to and returned from setIndex and getIndex().

Parameters:

index - the desired index in the input text.

Returns:

the first normalized character that is the result of iterating forward starting at the given index.

Throws:

IllegalArgumentException - if the given index is less than getBeginIndex() or greater than getEndIndex().

Status:

Obsolete. Will be removed in ICU 3.2.

getBeginIndex

@Deprecated
public int getBeginIndex()

Deprecated. ICU 2.2. Use startIndex() instead.

Retrieve the index of the start of the input text. This is the begin index of the CharacterIterator or the start (i.e. 0) of the String over which this Normalizer is iterating

Returns:

The codepoint as an int

See Also:

startIndex()

getEndIndex

@Deprecated
public int getEndIndex()

Deprecated. ICU 2.2. Use endIndex() instead.

Retrieve the index of the end of the input text. This is the end index of the CharacterIterator or the length of the String over which this Normalizer is iterating

Returns:

The codepoint as an int

See Also:

endIndex()

first

@Deprecated
public int first()

Deprecated. ICU 56

Return the first character in the normalized text. This resets the Normalizer's position to the beginning of the text.

Returns:

The codepoint as an int

last

@Deprecated
public int last()

Deprecated. ICU 56

Return the last character in the normalized text. This resets the Normalizer's position to be just before the the input text corresponding to that normalized character.

Returns:

The codepoint as an int

getIndex

@Deprecated
public int getIndex()

Deprecated. ICU 56

Retrieve the current iteration position in the input text that is being normalized. This method is useful in applications such as searching, where you need to be able to determine the position in the input text that corresponds to a given normalized output character.

Note: This method sets the position in the input, while next() and previous() iterate through characters in the output. This means that there is not necessarily a one-to-one correspondence between characters returned by next and previous and the indices passed to and returned from setIndex and getIndex().

Returns:

The current iteration position

startIndex

@Deprecated
public int startIndex()

Deprecated. ICU 56

Retrieve the index of the start of the input text. This is the begin index of the CharacterIterator or the start (i.e. 0) of the String over which this Normalizer is iterating

Returns:

The current iteration position

endIndex

@Deprecated
public int endIndex()

Deprecated. ICU 56

Retrieve the index of the end of the input text. This is the end index of the CharacterIterator or the length of the String over which this Normalizer is iterating

Returns:

The current iteration position

setMode

@Deprecated
public void setMode(Normalizer.Mode newMode)

Deprecated. ICU 56

Set the normalization mode for this object.

Note:If the normalization mode is changed while iterating over a string, calls to next() and previous() may return previously buffers characters in the old normalization mode until the iteration is able to re-sync at the next base character. It is safest to call setText(), first(), last(), etc. after calling setMode.

Parameters:

newMode - the new mode for this Normalizer. The supported modes are:

• NFC - Unicode canonical decompositiion followed by canonical composition.
• NFKC - Unicode compatibility decompositiion followed by canonical composition.
• NFD - Unicode canonical decomposition
• NFKD - Unicode compatibility decomposition.
• NONE - Do nothing but return characters from the underlying input text.

getMode()

getMode

@Deprecated
public Normalizer.Mode getMode()

Deprecated. ICU 56

Return the basic operation performed by this Normalizer

See Also:

setMode(com.ibm.icu.text.Normalizer.Mode)

setOption

@Deprecated
public void setOption(int option,
                                  boolean value)

Deprecated. ICU 56

Set options that affect this Normalizer's operation. Options do not change the basic composition or decomposition operation that is being performed , but they control whether certain optional portions of the operation are done. Currently the only available option is:

• UNICODE_3_2 - Use Normalization conforming to Unicode version 3.2.

Parameters:

option - the option whose value is to be set.

value - the new setting for the option. Use true to turn the option on and false to turn it off.

See Also:

getOption(int)

getOption

@Deprecated
public int getOption(int option)

Deprecated. ICU 56

Determine whether an option is turned on or off.

See Also:

setOption(int, boolean)

getText

@Deprecated
public int getText(char[] fillIn)

Deprecated. ICU 56

Gets the underlying text storage

Parameters:

fillIn - the char buffer to fill the UTF-16 units. The length of the buffer should be equal to the length of the underlying text storage

Throws:

IndexOutOfBoundsException - If the index passed for the array is invalid.

See Also:

getLength()

getLength

@Deprecated
public int getLength()

Deprecated. ICU 56

Gets the length of underlying text storage

Returns:

the length

getText

@Deprecated
