| /** |
| * 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. |
| * |
| * Returns: the break type of @c |
