A grapheme functions is not locale dependency. This RFC is add locale parameter for grapheme case insensitive functions. That is more enhancements for Unicode can be expected.
By this RFC can cover locale. For example.
var_dump(grapheme_stripos("i", "\u{0130}", 0, "tr_TR")); // Result is 0
var_dump(grapheme_stripos("i", "\u{0130}", 0, "en_US")); // Result is false
Add a $locale parameter in these functions.
function grapheme_stripos(string $haystack, string $needle, int $offset = 0, ?string $locale = null): int|false function grapheme_strripos(string $haystack, string $needle, int $offset = 0, ?string $locale = null): int|false function grapheme_stristr(string $haystack, string $needle, bool $beforeNeedle = false, ?string $locale = null): string|false function grapheme_levenshtein(string $string1, string $string2, int $insertion_cost = 1, int $replacement_cost = 1, int $deletion_cost = 1, ?string $locale = null): int|false
