CJK Unified Ideographs Extension I block is not covered in `15.1.0-scripts.txt`

[JLHwung]

The CJK Unified Ideographs Extension I block 2EBF0..2EE5D is sorta last-minute changes included in the Unicode 15.1 (c.f. L2/23-114R). It was not included in the draft fetched as of March 2023.

There might be other changes that are not in my radar, I suggest we fetch the UCD again and update the data.

I’ve updated to the latest draft data now.

Some Block and Line_Break names are now getting recognized as “undefined”: node-unicode/unicode-15.1.0@f7936fc Either there is a bug in the data file format, or if it’s an intentional change, we have to update our parser. I’ll keep this issue open until this is fixed.

https://github.com/node-unicode/unicode-15.1.0/blob/f7936fca50ce6bf9ccce1e189ed0658380910a03/Block/undefined/regex.js#L1

U+0870 is from Arabic Extended-B introduced in Unicode 14, which happens to be not included in https://github.com/mathiasbynens/unicode-loose-match/blob/master/data/mappings.js. Since unicode-loose-match is built on Unicode 11, I suggest we update the data for unicode-loose-match and see if the new blocks introduced after Unicode 11 can be recognized.

I just published unicode-loose-match@2.6.0 containing those changes.

[JLHwung]

I can confirm that Blocks/undefined is gone after unicode-loose-match is bumped to 2.6.0. We may want to publish the updated packages unicode-12.0.0 .. unicode-15.0.0 as well, since they all benefit from the unicode-loose-match update.

[mathiasbynens]

I believe this has been resolved. Please comment & reopen if I missed anything!

[JLHwung]

Umm, it seems that the unicode-loose-match is not actually bumped because I don't observe any changes from unicode-15.1.0@1.4.2 to unicode-15.1.0@1.5.0: https://github.com/node-unicode/unicode-15.1.0/compare/v1.4.2..v1.5.0

It should be fixed in #72.

@mathiasbynens Can you cut the new release?

[mathiasbynens]

Done! See the v1.5.2 releases.

Thanks. I am wondering why https://github.com/node-unicode/unicode-15.1.0/blob/main/Block/undefined/regex.js is not removed, maybe we should clean up the output folder before publish? Anyway it is not emergent and we can fix that in the next regular update.
