Adobe’s open source projects and Ken’s contribution to those:

  • AGL and AGLFN (Adobe Glyph List) maps glyph names to Unicode values
  • CMap Resources are used to unidirectionally map character codes
  • CSS Orientation Test are lightweight and special-purpose OpenType fonts that map all Unicode code points to glyphs that indicate their orientation based on the writing direction.
  • Kenten Generic OpenType Font  provides glyphs suitable for typesetting emphasis marks in Japanese.
  • Mapping Resources for PDF are used to derive content from PDF files that include CJK (Chinese, Japanese, and Korean) information.
