Verify that 'text-transform: full-size-kana' is supported by comparing the visual rendering. 3. Use VoiceOver to compare the speech rendering. Additional Information: https://www.w3.org/TR/css-text-3/#text-transform-property Note that the mapping in the Small Kana Mapping Table is not a case mapping. These are different letters (with related, but different pronunciations) that happen to look similar. See examples in spec. 1977529 1 webkit-bug-importer 2023-09-14 10:56:17 -0700 <rdar://problem/115504070> 1977531 2 jcraig 2023-09-14 11:02:51 -0700 From some discussion with Elika, this might need to be limited to ruby, or at a minimum, we’d need test cases to make sure the other values (like text-transform: uppercase) were not affected by the change. Note that I’m still unclear as to why text-transform would be used in a way that affects the core meaning of the text, so perhaps we should discuss or require addition information before the change. 2033624 3 fantasai.bugs 2024-05-06 19:51:22 -0700 > Note that I’m still unclear as to why text-transform would be used in a way that affects the core meaning of the text, so perhaps we should discuss or require addition information before the change. This is explained in detail in the spec (linked above). 2042829 4 fantasai.bugs 2024-06-24 14:52:48 -0700 `full-width` should also get the same treatment (use underlying untransformed text for AT), fwiw. 2051681 5 jcraig 2024-08-09 10:23:07 -0700 I disagree about `full-width`... That's mostly likely an AT bug in automatic language detection; the characters are unambiguous, but the AT is choosing the wrong voice language. Filed <rdar://133412477> for that. I'll also file a CSS spec issue for the "casing for accessibility" note, because it doesn't take into account the spacing context we discussed for AT like HoverText where rendered `full-width` chars would be expected. 2052117 6 472124 fantasai.bugs 2024-08-12 10:52:26 -0700 Created attachment 472124 testcase 2052178 7 jcraig 2024-08-12 14:39:20 -0700 FYI fantasai: https://github.com/w3c/csswg-drafts/issues/10732 2052449 8 jhoffman23 2024-08-13 12:35:30 -0700 Pull request: https://github.com/WebKit/WebKit/pull/32125 2052820 9 ews-feeder 2024-08-14 14:40:54 -0700 Committed 282258@main (00c8f4758364): <https://commits.webkit.org/282258@main> Reviewed commits have been landed.
