I understand this. The "problem" is that Arial does not have a
the "subscript 2" character but it gets displayed properly in the
FXFontSelector. How does it do this? It does not display properly
in FXFontSelector for several other fonts which do not have the
"subscript 2" character...I just see the empty square character,
this is what I expect.

Make sure both are using the same font and pitch.  Not all fonts
have the full unicode repertoire in them; in fact, most fonts
have only a fraction of the full repertoire of glyphs.
