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.

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.
