39 * g_unichar_break_type:
40 * @c: a Unicode character
42 * Determines the break type of @c. @c should be a Unicode character
43 * (to derive a character from UTF-8 encoded text, use
44 * g_utf8_get_char()). The break type is used to find word and line
45 * breaks ("text boundaries"), Pango implements the Unicode boundary
46 * resolution alogorithms and normally you would use a function such
47 * as pango_break() instead of caring about break types yourself.
49 * Return value: break type
