mbstring doesn't deal with, or handle, locales, only charactersets. So that wouldn't be a good fit either. There is grapheme_stripos, but that also doesn't do it locale dependent: <https://www.php.net/manual/en/function.grapheme-stripos.php> PHP could really do with a locale aware, grapheme aware, set of Text utilities. I have a prototype at <https://github.com/derickr/php-text> where this suggested function also would fit in. cheers Derick
