<para>
|
|
This section describes a number of functions for dealing with
|
|
Unicode characters and strings. There are analogues of the
|
|
traditional <filename>ctype.h</filename> character classification
|
|
and case conversion functions, UTF-8 analogues of some string utility
|
|
functions, functions to perform normalization, case conversion and
|
|
collation on UTF-8 strings and finally functions to convert between
|
|
the UTF-8, UTF-16 and UCS-4 encodings of Unicode.
|
|
</para>
|
|
|
|
<para>
|
|
The implementations of the Unicode functions in GLib are based
|
|
on the Unicode Character Data tables, which are available from
|
|
<ulink url="http://www.unicode.org/">www.unicode.org</ulink>.
|
|
GLib 2.8 supports Unicode 4.0, GLib 2.10 supports Unicode 4.1,
|
|
GLib 2.12 supports Unicode 5.0, GLib 2.16.3 supports Unicode 5.1.

<para>
|
|
A type which can hold any UTF-32 or UCS-4 character code, also known
|
|
as a Unicode code point.
|
|
</para>
|
|
<para>
|
|
To print/scan values of this type to/from text you need to convert
|
|
to/from UTF-8, using g_utf32_to_utf8()/g_utf8_to_utf32().
|
|
</para>
|
|
<para>
|

To print/scan values of this type as integer, use
|
|
%G_GINT32_MODIFIER and/or %G_GUINT32_FORMAT.
|
|
</para>
|
|
<para>
|
|
The notation to express a Unicode code point in running text is as a
|
|
hexadecimal number with four to six digits and uppercase letters, prefixed
|
|
by the string "U+". Leading zeros are omitted, unless the code point would
|
|
have fewer than four hexadecimal digits.
|
|
For example, "U+0041 LATIN CAPITAL LETTER A".
|
|
To print a code point in the U+-notation, use the format string
|
|
"U+%04"G_GINT32_FORMAT"X".
|
|
To scan, use the format string "U+%06"G_GINT32_FORMAT"X".
|
|
<informalexample>
|
|
<programlisting>
|
|
gunichar c;
|
|
sscanf ("U+0041", "U+%06"G_GINT32_FORMAT"X", &c)
|
|
g_print ("Read U+%04"G_GINT32_FORMAT"X", c);

|
<firstterm>surrogate pairs</firstterm> to encode characters beyond the
|
|
BMP as pairs of 16bit numbers. Surrogate pairs cannot be stored in a

single gunichar2 field, but all GLib functions accepting gunichar2 arrays
|
|
will correctly interpret surrogate pairs.</footnote>.

<!-- ##### MACRO g_utf8_next_char ##### -->
|
|
<para>
|
|
Skips to the next character in a UTF-8 string. The string must be
|
|
valid; this macro is as fast as possible, and has no error-checking.
|
|
You would use this macro to iterate over a string character by
|
|
character. The macro returns the start of the next UTF-8 character.
|
|
Before using this macro, use g_utf8_validate() to validate strings
|
|
that may contain invalid UTF-8.

@p: Pointer to the start of a valid UTF-8 character.

|
|
<para>
|
|
Defines how a Unicode string is transformed in a canonical
|
|
form, standardizing such issues as whether a character with an accent is
|
|
represented as a base character and combining accent or as a single precomposed
|
|
character. Unicode strings should generally be normalized before comparing them.
|
|
</para>
|
|
|
|
@G_NORMALIZE_DEFAULT: standardize differences that do not affect the
|
|
text content, such as the above-mentioned accent representation.
|
|
@G_NORMALIZE_NFD: another name for %G_NORMALIZE_DEFAULT.
|
|
@G_NORMALIZE_DEFAULT_COMPOSE: like %G_NORMALIZE_DEFAULT, but with composed
|
|
forms rather than a maximally decomposed form.
|
|
@G_NORMALIZE_NFC: another name for %G_NORMALIZE_DEFAULT_COMPOSE.
|
|
@G_NORMALIZE_ALL: beyond %G_NORMALIZE_DEFAULT also standardize the
|
|
"compatibility" characters in Unicode, such as SUPERSCRIPT THREE to the
|
|
standard forms (in this case DIGIT THREE). Formatting information may be
|
|
lost but for most text operations such characters should be considered the
|
|
same.
|
|
@G_NORMALIZE_NFKD: another name for %G_NORMALIZE_ALL.
|
|
@G_NORMALIZE_ALL_COMPOSE: like %G_NORMALIZE_ALL, but with composed
|
|
forms rather than a maximally decomposed form.
|
|
@G_NORMALIZE_NFKC: another name for %G_NORMALIZE_ALL_COMPOSE.
