> This is the only place in WebKit that requires a full Unicode case matching. Can you specify in more detail what do you mean by full Unicode case matching here? Do you mean case-sensitive matching? I understand the current spec to mean: Perform "Default Caseless Matching" from https://www.unicode.org/versions/Unicode9.0.0/ch03.pdf section 3.13, with emphasis on doing that without normalization and without language specifc tailorings. This would be only the comparison mentioned in the Unicode spec as D144: > D144 A string X is a caseless match for a string Y if and only if: > toCasefold(X) = toCasefold(Y) Implementation wise, I believe this would be http://icu-project.org/apiref/icu4c/classicu_1_1UnicodeString.html#a0924f873180947aab38b7380da638533 with `U_FOLD_CASE_EXCLUDE_SPECIAL_I`. I think the spec already describes that this flag should be set accordingly, as tailorings are excluded from the matching algorithm. What performance benefits do you see from only performing casefolding for the ASCII range? -- GitHub Notification of comment by drott Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/3675#issuecomment-467363173 using your GitHub account
