Fixed crashes when Fl_Text_* detects illegal UTF 8 sequences. Widgets will not do any further processing but just jump over the character. Screen representation depends largely on whatever the underlying OS does with those sequences, but I feel that this is out of the scope of this library. (STR 2348)
