Function Documentation

int i18n_uchar_char_age	(	i18n_uchar32	c,
		i18n_uversion_info	version_array
	)

Gets the "age" of the code point.

The "age" is the Unicode version when the code point was first designated (as a non-character or for private use) or assigned a character. This can be useful to avoid emitting code points to receiving processes that do not accept newer characters.

Since :: 4.0

Parameters:

[in]	c	The code point
[in]	version_array	The Unicode version number array, to be filled in

Returns:: 0 on success, otherwise a negative error value

Return values:

I18N_ERROR_NONE	Successful
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter

int i18n_uchar_char_digit_value	(	i18n_uchar32	c,
		int32_t *	char_digit_value
	)

Returns the decimal digit value of a decimal digit character.

Such characters have the general category "Nd" (decimal digit numbers) and a i18n_uchar_u_numeric_type_e of I18N_UCHAR_U_NT_DECIMAL. Unlike ICU releases before 2.6, no digit values are returned for any Han characters because Han number characters are often used with a special chinese-style number format (with characters for powers of 10 in between) instead of in decimal-positional notation. Unicode 4 explicitly assigns Han number characters the i18n_uchar_u_numeric_type_e I18N_UCHAR_U_NT_NUMERIC instead of I18N_UCHAR_U_NT_DECIMAL. See jitterbug 1483 for more details. Use i18n_uchar_get_int_property_value() and i18n_uchar_get_numeric_value() for complete numeric unicode properties.

Since :: 4.0

Parameters:

[in]	c	The code point for which to get the decimal digit value
[out]	char_digit_value	The decimal digit value of c, or `-1` if c is not a decimal digit character

Returns:: 0 on success, otherwise a negative error value

Return values:

I18N_ERROR_NONE	Successful
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter

See also:: i18n_uchar_get_numeric_value()

int i18n_uchar_char_direction	(	i18n_uchar32	c,
		i18n_uchar_direction_e *	direction
	)

Returns the bidirectional category value for the code point.

Which is used in the unicode bidirectional algorithm (UAX #9 Unicode reports). Note that some unassigned code points have bidi values of R or AL because they are in blocks that are reserved for right-to-left scripts. Same as java.lang.Character.getDirectionality()

Since :: 4.0

Parameters:

[in]	c	The code point to be tested
[out]	direction	The bidirectional category (i18n_uchar_direction_e) value

Returns:: 0 on success, otherwise a negative error value

Return values:

I18N_ERROR_NONE	Successful
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter

See also:: i18n_uchar_direction_e

int i18n_uchar_char_from_name	(	i18n_uchar_u_char_name_choice_e	name_choice,
		const char *	name,
		i18n_uchar32 *	char_from_name
	)

Finds a unicode character by its name and return its code point value.

The name is matched exactly and completely. If the name does not correspond to a code point, I18N_ERROR_INVALID_CHAR_FOUND is returned. A unicode 1.0 name is matched only if it differs from the modern name. Unicode names are all uppercase. Extended names are lowercase followed by an uppercase hexadecimal number, and within angle brackets.

Since :: 4.0

Parameters:

[in]	name_choice	Selector for which name to match
[in]	name	The name to match
[out]	char_from_name	The Unicode value of the code point with the given name, or an undefined value if there is no such code point

Returns:: 0 on success, otherwise a negative error value

Return values:

I18N_ERROR_NONE	Successful
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter

See also:: i18n_uchar_enum_char_names(); i18n_uchar_char_name(); i18n_uchar_u_char_name_choice_e

int i18n_uchar_char_mirror	(	i18n_uchar32	c,
		i18n_uchar32 *	char_mirror
	)

Maps the specified character to a "mirror-image" character.

For characters with the bidi_mirrored property, implementations sometimes need a "poor man's" mapping to another unicode character (code point) such that the default glyph may serve as the mirror-image of the default glyph of the specified character. This is useful for text conversion to and from codepages with visual order, and for displays without glyph selection capabilities.

Since :: 4.0

Parameters:

[in]	c	The code point to be mapped
[out]	char_mirror	Another Unicode code point that may serve as a mirror-image substitute, or c itself if there is no such mapping or c does not have the Bidi_Mirrored property

Returns:: 0 on success, otherwise a negative error value

Return values:

I18N_ERROR_NONE	Successful
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter

See also:: I18N_UCHAR_BIDI_MIRRORED; i18n_uchar_is_mirrored()

int i18n_uchar_char_name	(	i18n_uchar32	code,
		i18n_uchar_u_char_name_choice_e	name_choice,
		char *	buffer,
		int32_t	buffer_length,
		int32_t *	name_length
	)

Retrieves the name of a unicode character.

Depending on name_choice, the character name written into the buffer is the "modern" name or the name that was defined in unicode version 1.0. The name contains only "invariant" characters like a-z, 0-9, space, and '-'. unicode 1.0 names are only retrieved if they are different from the modern names and if the data file contains the data for them.

Since :: 4.0

Parameters:

[in]	code	The character (code point) for which to get the name. It must be `0 <= code <= 0x10ffff`.
[in]	name_choice	Selector for which name to get.
[in]	buffer	Destination buffer for copying the name. The name will always be zero-terminated. If there is no name, then the buffer will be set to the empty string.
[in]	buffer_length	The length of the buffer
[out]	name_length	The length of the name, or 0 if there is no name for this character. If the bufferLength is less than or equal to the length, then the buffer contains the truncated name and the returned length indicates the full length of the name. The length does not include the zero-termination.

Returns:: 0 on success, otherwise a negative error value

Return values:

I18N_ERROR_NONE	Successful
I18N_ERROR_INVALID_PARAMETER	Invalid function parameter

		int8_t	radix,
		int32_t *	numerical_value
	)

Returns the decimal digit value of the code point in the specified radix.

If the radix is not in the range 2<= radix <= 36 or if the value of c is not a valid digit in the specified radix, -1 is returned. A character is a valid digit if at least one of the following is true:

The character has a decimal digit value. Such characters have the general category "Nd" (decimal digit numbers) and a I18N_UCHAR_NUMERIC_TYPE of I18N_UCHAR_U_NT_DECIMAL. In this case the value is the character's decimal digit value.
The character is one of the uppercase Latin letters 'A' through 'Z'. In this case the value is c - 'A' + 10.
The character is one of the lowercase Latin letters 'a' through 'z'. In this case the value is ch - 'a' + 10.
Latin letters from both the ASCII range (0061..007A, 0041..005A) as well as from the Fullwidth ASCII range (FF41..FF5A, FF21..FF3A) are recognized.

int i18n_uchar_enum_char_types	(	i18n_uchar_enum_char_type_cb	cb,
		const void *	user_data
	)

Enumerates efficiently all code points with their unicode general categories.

This is useful for building data structures (e.g., unicode_set's), for enumerating all assigned code points ( type != I18N_UCHAR_U_UNASSIGNED), etc.for each contiguous range of code points with a given general category ("character type"), the i18n_uchar_enum_char_type_cb() function is called. Adjacent ranges have different types. The unicode standard guarantees that the numeric value of the type is 0..31.

Since :: 4.0

Parameters:

[in]	cb	A pointer to a function that is called for each contiguous range of code points with the same general category
[in]	user_data	An opaque pointer that is passed on to the callback function

int i18n_uchar_fold_case	(	i18n_uchar32	c,
		uint32_t	options,
		i18n_uchar32 *	code_point
	)

Maps the given character to its case folding equivalent.

If the character has no case folding equivalent, the character itself is returned. This function only returns the simple, single-code point case mapping. Full case mappings should be used whenever possible because they produce better results by working on whole strings. They take into account the string context and the language and can map to a result string with a different length as appropriate. Full case mappings are applied by the string case mapping functions, see utils_i18n_ustring.h. See also the user guide chapter on c/posix migration: User Guide: Case Mappings

Since :: 4.0

Parameters:

[in]	c	The code point to be mapped
[in]	options	Either I18N_U_FOLD_CASE_DEFAULT or I18N_U_FOLD_CASE_EXCLUDE_SPECIAL_I
[out]	code_point	The I18N_UCHAR_SIMPLE_CASE_FOLDING of the code point, if any; otherwise the code point itself.

Returns:: 0 on success, otherwise a negative error value

If the value of radix is not a valid radix, or the value of digit is not a valid digit in the specified radix, the null character (u+0000) is returned. The radix argument is valid if it is greater than or equal to 2 and less than or equal to 36. The digit argument is valid if 0 <= digit < radix. If the digit is less than 10, then '0' + digit is returned. Otherwise, the value 'a' + digit - 10 is returned. Same as java.lang.Character.forDigit().

int i18n_uchar_get_numeric_value	(	i18n_uchar32	c,
		double *	numeric_val
	)

Gets the numeric value for a Unicode code point as defined in the Unicode Character Database.

A "double" param type is necessary because some numeric values are fractions, negative, or too large for int32_t. For characters without any numeric values in the Unicode Character Database, numeric_val will be equal to I18N_U_NO_NUMERIC_VALUE. Note: This is different from the Unicode Standard which specifies NaN as the default value. (NaN is not available on all platforms) This function is similar to java.lang.Character.getNumericValue(), but i18n_uchar_get_numeric_value() also supports negative values, large values, and fractions, while Java's getNumericValue() returns values 10..35 for ASCII letters.

Since :: 4.0

Parameters:

[in]	c	The code point to get the numeric value for
[out]	numeric_val	The numeric value of c or I18N_U_NO_NUMERIC_VALUE if none is defined

[in]	property	#18n_uchar_uproperty_e selector other than I18N_UCHAR_INVALID_CODE. If out of range, NULL is returned.
[in]	name_choice	Selector for which name to get. If out of range, NULL is returned. All properties have a long name. Most have a short name, but some do not. Unicode allows for additional names; if present these will be returned by `I18N_UCHAR_U_LONG_PROPERTY_NAME + i`, where `i = 1, 2,..`.
[out]	name	A pointer to the name, or NULL if either the property or the name_choice is out of range. If a given name_choice returns NULL, then all larger values of name_choice will return NULL, with one exception: if NULL is returned for I18N_UCHAR_U_SHORT_PROPERTY_NAME, then I18N_UCHAR_U_LONG_PROPERTY_NAME (and higher) may still return a non-NULL value. The returned pointer is valid until 18n_uclean_cleanup() (not implemented) is called.

Returns:: 0 on success, otherwise a negative error value

[out]	value_enum	A value integer or I18N_UCHAR_INVALID_CODE if the given name does not match any value of the given property, or if the property is invalid. Note: I18N_UCHAR_GENERAL_CATEGORY_MASK values are not values of i18n_uchar_category_e, but rather mask values produced by I18N_U_GET_GC_MASK(). This allows grouped categories such as [:L:] to be represented.

Returns:: 0 on success, otherwise a negative error value

I18N_UCHAR_GENERAL_CATEGORY_MASK values are not values of i18n_uchar_category_e, but rather mask values produced by I18N_U_GET_GC_MASK(). This allows grouped categories such as [:L:] to be represented. Mask values range non-contiguously from 1..I18N_U_GC_P_MASK.
[in]	name_choice	Selector for which name to get. If out of range, NULL is returned. All values have a long name. Most have a short name, but some do not. Unicode allows for additional names; if present these will be returned by `I18N_UCHAR_U_LONG_PROPERTY_NAME + i`, where `i = 1, 2,..`.
[out]	name	A pointer to the name, or NULL if either the property or the name_choice is out of range.

int i18n_uchar_is_whitespace	(	i18n_uchar32	c,
		i18n_ubool *	is_whitespace
	)

Determines if the specified code point is a whitespace character according to Java/ICU.

A character is considered to be a Java whitespace character if and only if it satisfies one of the following criteria:

It is a Unicode Separator character (categories "Z" = "Zs" or "Zl" or "Zp"), but is not also a non-breaking space (U+00A0 NBSP or U+2007 Figure Space or U+202F Narrow NBSP).
It is U+0009 HORIZONTAL TABULATION.
It is U+000A LINE FEED.
It is U+000B VERTICAL TABULATION.
It is U+000C FORM FEED.
It is U+000D CARRIAGE RETURN.
It is U+001C FILE SEPARATOR.
It is U+001D GROUP SEPARATOR.
It is U+001E RECORD SEPARATOR.
It is U+001F UNIT SEPARATOR.

This api tries to sync with the semantics of Java's java.lang.Character.isWhitespace(), but it may not return the exact same results because of the Unicode version difference. Note: unicode 4.0.1 changed u+200_b zero width space from a space separator (Zs) to a format control (Cf). Since then, i18n_uchar_is_whitespace(0x200b) returns false. See Unicode 4.0.1 Note: there are several icu whitespace functions. Please see the uchar.h file documentation for a detailed comparison.
