And indeed they are missing from https://unicode.org/Public/UNIDATA/CaseFolding.txt But OTOH, I can't find the file CaseFolding.txt in admin/unidata. This means Emacs doesn't use this file? Then should we add more case-folding information explicitly for this Unicode block? Case-folding is already supported for some characters from other Unicode blocks such e.g. FULLWIDTH LATIN CAPITAL LETTERs, CIRCLED LATIN CAPITAL LETTERs, etc. But e.g. PARENTHESIZED LATIN CAPITAL LETTERs are missing too. What is worse is that in Emacs ⒜ doesn't have even a word syntax like its counterpart 🄐.
