That would probably be because you don't have this particular font. It uses a Unicode range for 
"Manufacturer Specific" stuff..

Ok, I tried converting $F080 to UTF-8 and inserting it that way, but I got an odd symbol that was 
not what I was expecting. I'll play with it some more.

For testing can I just manually convert to 3 byte UTF-8 and insert it like
Edit1.Text := Char($EF) + Char($82) + Char($80);

Because :

A) on Linux/gtk2 it displays the correct glyph when I use WideChar($F080)

B) I went through the font in FontForge and checked that the glyphs are assigned in the correct places.

I have this working flawlessly on Linux / GTK2, I just can't get it to work on Mac/Carbon.

I'll have a play with using UTF-8 instead of WideChar again. I did try it, and I got a glyph, just 
not one that exists in this Font set.

Cheers for the advice guys :)
