Hi, Claude and Internals

Thank you for your feedback.
Indeed, I keep only locale is case-sensitive.

However, I watched that RFC: https://wiki.php.net/rfc/strtolower-ascii
and https://github.com/php/php-src/pull/7511,
Perhaps, I should not locale-dependant for grapheme functions.

I'll think about it more deeply.
Please give me a time.

Regards
Yuya
