/* Gabriel Landini's Voynich Eva Hand 1 fonts.
   EVA2.ttf — 2025 update, from https://voynich.nu/Fonts/EVA2.ttf
   EVA1.ttf — original 1998 release, from evah1_1.zip
   Non-commercial research use per voynich.nu/roadmap.html#fonts.
   Encoding: direct ASCII — 'a' at U+0061, 'c' at U+0063, 'h' at U+0068 etc.
   High-ASCII range U+0080-U+00FF is used for rare extended glyphs.
   Combined font stack — EVA2 primary + EVA1 fallback — gives us ~72 of the
   98 @NNN; rare extended glyph codes used in the STA alphabet. */
