We shouldn't do that, IMHO. FLTK is not a text processing program.

nedit, notepad++, editpad, and even Windows notepad display cp1252.txt (yes,
that with 'native' encoding) correctly, including the soft hyphen as a visible
character. Let's do it this way, I'd say.
I also tried FLTK 2.0 with cp1252_utf-8.txt, and it works like a charm. Even
0x98 (U+02DC, SMALL TILDE) is displayed and handled correctly (WRT cursor
movement). No line length problems as in FLTK 1.3 - maybe we should have a look
at FLTK 2's implementation?

IMHO not, see above. Maybe later...

This would make it (IMHO) unnecessarily complex, see above.
