  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);
