The mark2X.ttf and mark2X.otf files also contain just a glyph for the +character X but the glyph is similar to the space mark character. The markXmark2Y.ttf has +two glyphs, the first glyph for X and the second glyph for Y. + +The markA.eot and markB.eot files are for EOT-related testing. The markA.eot file is just +a copy of markA.ttf while markB.eot is a valid EOT file embedding the contents of markB.ttf +with a null root string (so it can be used in IE without domain-specific restrictions). + + +PositioningTest1.ttf, PositioningTest2.ttf + +These fonts were generated with FontForge and then OpenType tables added with MS VOLT. +The glyphs are from Charis SIL (see http://scripts.sil.org/CharisSILFont), released under the +Open Font License. + +In both fonts, the lowercase 'o' glyph should appear raised when rendered. Font 1 uses a GPOS +positioning rule to achieve this, so it tests whether vertical deltas are being handled +correctly. Font 2 uses a GSUB substitution to replace the 'o' with a glyph that has already +been offset within the em-square, so no vertical delta is involved. + +Finally, the capital 'O' character maps directly to the shifted 'o' glyph, so this can be +used for comparison without requiring any OpenType layout support. -- cgit v1.2.3
