Changelog

Sourced from ttfunk's changelog.

[1.8.0][] - 2024-03-05

Fixed

  • Corrupted CFF index data

    there was a subtle bug in cff index implementation that resulted in a data corruption. in certain circumstances some items didn't get properly encoded. this happened when items were not previously accessed.

    this resulted, for instance, in missing glyphs. but only sometimes because indexes might've still contain data that shouldn't've been there. in combination with incorrect encoding (see further) this resulted in some glyphs still being rendered, sometimes even correctly.

    along with the fix a rather large api change landed. this resulted in quite a big diff.

  • Incorrect CFF encoding in subsets

    TTFunk used to reuse encoding from the original font. This mapping was incorrect for subset fonts which used not just a subset of glyphs but also a different encoding.

    A separate issue was that some fonts have empty CFF encoding. This incorrect mapping resulted in encoding that mapped all codes to glyph 0.

    This had impact on Prawn in particular. PDF spec explicitly says that CFF encoding is not to be used in OpenType fonts. cmap table should directly index charstrings in the CFF table. Despite this PDF renderers still use CFF encoding to retrieve glyphs. So TTFunk has to discard the original CFF encoding and supply its own.

  • maxp table

    The table is now correctly parsed and encoded for both TrueType and CFF-based OpenType fonts.

  • Files are closed sooner

    Files were garbage collected but could stay open for longer than necessary.
