Bug Fixes

  • Justified text word spacing uses natural glyph advances (not Knuth-Plass adjusted widths)
  • Shaping cluster byte-to-char conversion for multi-byte characters
  • Standard font /Widths arrays in PDF font dictionaries
  • Cross-axis stretch propagation for flex children with alignItems: stretch
  • measure_intrinsic_width accounts for textTransform: 'uppercase'
