…ection The ligature glyphs were not included in the character coverage tables, causing incorrect word length calculation. Words containing ligatures had bold applied to wrong positions (middle instead of start). Fixed by adding ligature glyphs to coverage tables and substitution mappings in affected fonts: - Fast_Serif.ttf - fast-fonts-for-kindle/Fast_Serif/Fast_Serif.otf - fast-fonts-for-kindle/Fast_Serif/Fast_Serif_Italic.otf - fast-fonts-for-kindle/Fast_OpenDyslexic/Fast_OpenDyslexic.otf - fast-fonts-for-kindle/Fast_OpenDyslexic/Fast_OpenDyslexic_Italic.otf Also added test.html for local font preview and testing.
