+ 9.1.1 Text Run Rules
+ 9.1.2 Layout Rules

+ 9.1.3 Compression Rules
text-combine-upright-compression-001 = text-combine-upright, no compression
  • text-combine-upright with character not wider than 1em should not trigger compression.
text-combine-upright-compression-002 = text-combine-upright, compression of two characters
  • text-combine-upright should try applying 'hwid' feature if the width is wider than 1em
text-combine-upright-compression-003 = text-combine-upright, compression of three characters

  • text-combine-upright should try applying 'qwid' feature if the width is wider than 1em
text-combine-upright-compression-007 = text-combine-upright: all, fit any number of characters
  • text-combine-upright: all should allow any amount of text to be compressed in a 1em square
+ 9.1.3.1 Full-width Characters
full-width-001 As-IsRecommend CSS Writing Modes: 'text-combine-upright: all' applied on a single typographic full-width unit character
  • When 'text-combine-upright: all' and 'text-transform: full-width' are applied simultaneously on 1 single typographic unit or when 'text-combine-upright: all' is set on a full-width typographic unit character, then such typographic unit remains a full-width character.
full-width-002 As-IsRecommend CSS Writing Modes: 'text-combine-upright: all' applied on 2 full-width characters
  • When two or more full-width characters are combined, they are first converted to non-full-width characters.
text-combine-upright-compression-005 = text-combine-upright, no compression for single full-width character
  • text-combine-upright should not change a single full-width character
text-combine-upright-compression-005a = text-combine-upright, no compression for single character with full-width transform
  • text-combine-upright should not change a single full-width character
text-combine-upright-compression-006 = text-combine-upright, compression for two full-width characters
  • text-combine-upright should run the reverse of full-width transform before applying compression
text-combine-upright-compression-006a = text-combine-upright, compression for two characters with full-width transform
  • text-combine-upright should run the reverse of full-width transform before applying compression
text-transform-fullwidth-002 = text-transform: full-width (basic)
  • This test checks basic support of 'text-transform: full-width' in a vertical writing context. Since full-width Latin characters are typeset upright, then the characters of the text sample of this test should not be rotated toward the right but should be upright.
text-transform-fullwidth-004 = text-transform: full-width with 1 single digit (basic)
  • This test checks basic support of 'text-transform: full-width' in a vertical writing context. Since full-width digit characters are typeset upright, then the single digit character in the text sample should not be rotated toward the right but should be upright.
text-transform-fullwidth-005 = text-transform: full-width with 2 digits (basic)
  • This test checks basic support of 'text-transform: full-width' in a vertical writing context. Since full-width digit characters are typeset upright, then both digit characters in the text sample should not be rotated toward the right but should be upright. This is furthermore the case since, in this test, there is no 'text-combine-upright' in effect or applying to such pair of digits.
