Summary

  • Adds Fast Atkinson Hyperlegible fonts in OTF format (all 4 variants)
  • OTF versions work out-of-the-box on older Kindle devices (pre-5th generation)
  • Same speed-reading features as TTF versions

Files Added

  • Fast_Atkinson_Regular.otf - Regular variant in OTF format
  • Fast_Atkinson_Italic.otf - Italic variant in OTF format
  • Fast_Atkinson_Bold.otf - Bold variant in OTF format
  • Fast_Atkinson_BoldItalic.otf - Bold Italic variant in OTF format

Why OTF?

  • Better compatibility with older Kindles: Pre-5th generation Kindle devices have better support for OTF files
  • PostScript Type 2 outlines: Uses CFF (Compact Font Format) instead of TrueType outlines
  • Same features: Identical speed-reading functionality as TTF versions (PR Add Fast Atkinson Hyperlegible fonts #42)

Features

  • OpenType contextual alternates to automatically bold the first ~40% of each word
  • Explicit language system support (latn, grek, cyrl) for Kindle compatibility
  • Proper PANOSE classification for sans-serif font preview display
  • Creates visual fixation points for faster reading while maintaining accessibility

Note

For newer Kindles (5th generation and later), the TTF versions from PR #42 are recommended. These OTF files are primarily for:

  • Older Kindle devices (pre-5th gen)
  • Users who prefer OTF format
  • Print applications where PostScript outlines are preferred

🤖 Generated with Claude Code

Add OTF (OpenType with CFF outlines) versions of Fast Atkinson Hyperlegible fonts in Regular, Italic, Bold, and Bold Italic styles. These fonts work out-of-the-box on older Kindle devices (pre-5th generation) that may have better OTF support than TTF.

Features:
- OpenType format with PostScript Type 2 (CFF) outlines
- Better compatibility with older Kindle devices
- Same speed-reading features as TTF versions (~40% bold emphasis per word)
- Explicit language system support (latn, grek, cyrl)
- Proper PANOSE classification for sans-serif font preview display

Note: For newer Kindles (5th gen+), use the TTF versions from PR Born2Root#42. These OTF files are primarily for older devices or users who prefer OTF format.

Closing this PR in favor of #44 which includes the Fast Atkinson OTF fonts as part of a comprehensive Kindle-optimized font collection with complete 4-variant families, proper metadata, and additional font families (Fast OpenDyslexic, dotted variants).
