I found the header in Unicode Emoji 14.0 data files had changed slightly (and again at 15.0), but enc/unicode/case-folding.rb didn't follow it.
Then I fixed it and rebuilt the headers under enc/unicode/14.0.0, name2ctype.h had diffences from the master, as bellow.

CR_Lower, CR_Cased and CR_Other_Lowercase just seem misses in the previous operation, and no problems.

But U+11720..U+11721 in CR_Grapheme_Cluster_Break_SpacingMark is absent in the original data of the Unicode.org.
According to @naruse's investigation, it was removed at the commit Update to Unicode 14.0.0, while U+11720 is still SpacingMark in the latest https://www.unicode.org/reports/tr29/.

According to @naruse's investigation, it was removed at the commit [Update to Unicode 14.0.0], while U+11720 is still SpacingMark in the latest https://www.unicode.org/reports/tr29/.

Read https://www.unicode.org/reports/tr29/#SpacingMark again, and found U+11720 and U+11721 are listed as exceptions.

Exceptions: The following (which have General_Category = Spacing_Mark and would otherwise be included) are specifically excluded:

That means these are removed intentionally.

• Subject changed from Unicode tables differences from Unicode.org 14.0 data and removed properties since 13.0 to Unicode tables differences from Unicode.org 14.0 data

[duerst (Martin Dürst)]

The wrong properties were fixed for version 14.0.0 with commit e31d645. This issue should stay open until we are sure what caused the wrong properties in the first place.

@duerst (Martin Dürst) Is there any action for Ruby 3.2 related this? If there is nothing to do for Ruby 3.2, I'll remove this from Ruby 3.2 milestone.

• Target version deleted (3.2)

No, nothing should be needed for Ruby 3.2. I removed it myself.

BTW, can we add a "3.3" target version?

[hsbt (Hiroshi SHIBATA)]

Thanks. I did create the 3.3 milestone

@duerst (Martin Dürst) Did this issue reoccur in the update to Unicode 15? If not, do you think this can be closed?
