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

69 * in a single gunichar2 field, but all GLib functions accepting gunichar2
70 * arrays will correctly interpret surrogate pairs.</footnote>.
