Daniel Lemire recently wrote about optimizing UTF-16 surrogate pair correction: https://lemire.me/blog/2024/12/29/efficient-in-place-utf-16-unicode-correction-with-arm-neon/

WebKit does this kind of correction in WTF::replaceUnpairedSurrogatesWithReplacementCharacter.

Would be good to check if the technique is applicable.
