33 * gunichar:
34 *
35 * A type which can hold any UTF-32 or UCS-4 character code,
36 * also known as a Unicode code point.
37 *
38 * If you want to produce the UTF-8 representation of a #gunichar,
39 * use g_ucs4_to_utf8(). See also g_utf8_to_ucs4() for the reverse
40 * process.
41 *
42 * To print/scan values of this type as integer, use
43 * %G_GINT32_MODIFIER and/or %G_GUINT32_FORMAT.
44 *
45 * The notation to express a Unicode code point in running text is
46 * as a hexadecimal number with four to six digits and uppercase
47 * letters, prefixed by the string "U+". Leading zeros are omitted,
48 * unless the code point would have fewer than four hexadecimal digits.
49 * For example, "U+0041 LATIN CAPITAL LETTER A". To print a code point
50 * in the U+-notation, use the format string "U+\%04"G_GINT32_FORMAT"X".
51 * To scan, use the format string "U+\%06"G_GINT32_FORMAT"X".
52 *
53 * |[
54 * gunichar c;
55 * sscanf ("U+0041", "U+%06"G_GINT32_FORMAT"X", &amp;c)
56 * g_print ("Read U+%04"G_GINT32_FORMAT"X", c);

70 *

913 * @G_NORMALIZE_NFC: another name for %G_NORMALIZE_DEFAULT_COMPOSE
914 * @G_NORMALIZE_ALL: beyond %G_NORMALIZE_DEFAULT also standardize the
915 * "compatibility" characters in Unicode, such as SUPERSCRIPT THREE
916 * to the standard forms (in this case DIGIT THREE). Formatting
917 * information may be lost but for most text operations such
918 * characters should be considered the same
919 * @G_NORMALIZE_NFKD: another name for %G_NORMALIZE_ALL
920 * @G_NORMALIZE_ALL_COMPOSE: like %G_NORMALIZE_ALL, but with composed
921 * forms rather than a maximally decomposed form

925 * form, standardizing such issues as whether a character with
926 * an accent is represented as a base character and combining
927 * accent or as a single precomposed character. Unicode strings
928 * should generally be normalized before comparing them.
