/**

 * g_unichar_break_type:

 * @c: a Unicode character

 * 

 * Determines the break type of @c. @c should be a Unicode character

 * (to derive a character from UTF-8 encoded text, use

 * g_utf8_get_char()). The break type is used to find word and line

 * breaks ("text boundaries"), Pango implements the Unicode boundary

 * resolution algorithms and normally you would use a function such

 * as pango_break() instead of caring about break types yourself.

 * 

 * Return value: the break type of @c
