I tried implement mb_levenshtein function and create an RFC.
https://wiki.php.net/rfc/mb_levenshtein
https://github.com/php/php-src/pull/16043
I would like discussion, feel free to comment.
Thank you for your RFC. I share the concern raised by cmb in the PR
discussion:
https://github.com/php/php-src/pull/16043#issuecomment-2374574538
Generally working with codepoints is going to be confusing for a user,
but sometimes it is necessary when dealing with external systems that
themselves work with codepoints (MySQL comes to my mind). However
calculating the Levenshtein distance is most certainly something that
purely is "user-facing" and not constrained by external systems.
Calculating the distance of codepoints is going to be extremely
confusing when dealing with things like Emoji. It would probably best to
either only offer a `grapheme_*` function here or to leave this fully to
userland.
