Issue

how to remove only this type of special chars ░▒▓█► from a string in php I use this preg_replace('/[\x00-\x1F\x80-\xC0]/u', '',$string);

but i want to allow special char like à,â, ', ", for french language

Solution

You can use unicode character classes like \p{Latin} for latin script, \p{Sc} for currency, \p{P} (or shorter \pP) for punctuation characters:

$str = preg_replace('/[^0-9\p{Latin}\pP\p{Sc}@\s]+/u', '', $str);

You can find the different unicode character classes available in PCRE here. (search the sentence: "The following general category property codes are supported")
