Doc #81284 [Com]: str_getcsv cant parse with multibyte delimiter

Edit report at https://bugs.php.net/bug.php?id=81284&edit=1 ID: 81284 Comment by: mx03 at volny dot cz Reported by: mx03 at volny dot cz Summary: str_getcsv cant parse with multibyte delimiter Status: Open Type: Documentation Problem Package: Strings related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: If the delimiter is a utf8 string, one char is one char, even if it is multibyte. And the note sounds like str_getcsv support utf8 strings are fully supported. "The locale settings are taken into account by this function. If LC_CTYPE is e.g. en_US.UTF-8, strings in one-byte encodings may be read wrongly by this function." But it is only supported in the $string parameter, and not in the $separator. There should at least a note that describes this problem like with strlen only reads the amount of bytes.
