I believe that this is still available (and we're talking about FLTK 1.3, don't we?), but here we have the problem that we need to distinguish the number of characters and the number of bytes, which can be different, since we have the text in UTF-8 encoding. I think that the current (svn) version has been fixed to use the number of characters, so that the (fixed) buffer size mentioned above should probably be multiplied by 4 - however, it is still possible to use a *fixed* size.
