This sounds like it might be a font selection issue. Though that may depend on what host platform you are on... If your host is OSX, or a version of Windows from Vista or Win7, then the font rendering engine (provided by the OS) will attempt to substitute any missing glyphs from the current font with glyphs from a default fall-back font. This generally works very well, though you do sometimes see glyphs that look slightly "out of place" in your text as a result... However, older versions of Windows and our implementation on X11 systems, does not have that ability, so it is imperative that you set a font for the widget that can actually display the glyphs you are requesting, or you get these blanks. All I can suggest is that you try setting a few different font faces for your input widget and see how that affects the displayed text... Not ideal. Also, see the fonts demo in the test folder. Well, that's what I'd expect the problem to be for 1.1 or 1.3. There may be other differences in fltk-2 that I am not aware of, of course.
