The patch works, but you should also pass the AntiAliased parameter when
recursivly calling Glyph().
Besides this - I have the 0xA0 about 80 times in my epg.data (very often on
DMAX). As far as I can tell, the 0xA0 is used as NON-BREAKING SPACE to avoid the
collapsing of two or more spaces. Therefore the 0xA0 might as well be rendered
as normal single space by default:
if (CharCode == 0xA0)
CharCode = 0x20;
