CJK have not been considered since it's a separate case and no stripping is needed (I know Kenshi is taking care of those) DejaVuSans-Bold.ttf: 918 glyphs [125188 bytes] DejaVuSans-Oblique.ttf: 918 glyphs [126872 bytes] DejaVuSans.ttf: 918 glyphs [141668 bytes] nazlib.ttf: 303 glyphs [68448 bytes] nazli.ttf: 303 glyphs [55941 bytes] FreeSans.ttf: 2220 glyphs [292904 bytes] FreeSansBold.ttf: 1572 glyphs [131168 bytes] FreeSansOblique.ttf: 1333 glyphs [111580 bytes] KhmerOS.ttf: 539 glyphs [265988 bytes] TSCu_Paranar.ttf: 224 glyphs [63048 bytes] Font files: 10 Total size: 1382805 bytes Unique Glyphs: 2761 Bytes per glyph: 500 removing dejavu (or freefont if the new dejavu can cover everything), would simplify and reduce overhead (basic latin glyphs, as you mentioned above, are not stripped to preserve consistency: i.e. at least u0:u7f = 128 glyphs are included in each and every ttf file including bold/oblique) ciao, Davide
