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);
