Well, currently there is a little mess since we combine unicode and
non-unicode fonts (subtitles vs. OSD) and I tried to stay compatible with
the current osd code. That's why I prefer enumerating all glyphs and setting
all the tables first. Without this it would require testing all the fonts
where exactly the glyph is and the charset/charcode tables would be needed
all the time too. Another workaround is to try getting glyph indices for all
64k unicode characters but I'm not very fond of workarounds which can be
easily solved by upgrading.

this could be a clue, let's see.

I just thought it would be more acceptable for the BFU's and there is just
one OSD font anyway.
