I tried various combinations (albeit on windows and linux, my mac is not available just now) and I can't induce a fault - so the fault is possibly mac-specific... Anyway, what I find is that both "\xc2\xb1" and just the (not-valid-utf8) "\xb1" display a plusminus glyph on the display. I assume the later case is because ERRORS_TO_ISO8859_1 is set in fl_utf.c, so the bad "\xb1" falls-through to become U+00B1 anyway... Now, this probably works because both the *nix conversions and the win32 "char-by-char" conversions use fl_utf8decode() to do the conversion from utf8 to native. The win32 "string-by-string" conversions, and *I think* the Mac conversions, use fl_utf8toUtf16() instead, and it does not honour the ERRORS_TO_ISO8859_1 setting, so will fail on the "bad" string, I guess. Maybe that is key here? Anybody? On a related note, it is suggested (by people who know good stuff, e.g. Bill, Manolo) that the win32 conversions be converted to all be "string-by-string", dropping the old "char-by-char" mechanism. If we do, then ERRORS_TO_ISO8859_1 may also fail on win32 in future? Hmm, yup, just tested that by using the ::draw(int angle, const char* str...) version of the win32 draw text method, and indeed it fails, though does not cause a crash, just doesn't work...
