Subject: Let text widgets handle gracefully composed unicode characters -
 Cont'd.

This commit adds support of another type of composed characters: flags.
It also fixes Fl_Text_Buffer::prev_char() and Fl_Text_Buffer::next_char()
that must use Fl_Text_Buffer::byte_at() to access to the content of the text buffer.
