LiveType may not properly handle fonts that use ligatures, or that combine glyphs together.
Some fonts for languages such as Thai, Arabic, and Devanagri combine characters to make ligatures, or compound glyphs. Because LiveType handles each character as a separate glyph object, two glyphs that would normally be combined in a ligature may be rendered separately.
Fonts for Chinese, English, French, German, and Japanese should work correctly. Fonts that rely on ligatures to create "compound-glyphs" may not be handled correctly in LiveType.
