..and you can use Fl_Text_Buffer::add_modify_callback()
to set your callback to be invoked whenever the buffer
is modified, so you can do your per-character checks.
There are other ways to check for each character,
such as overriding the handle() method, but probably
add_modify_callback() is best..
