Nota:
A codificação interna ou a codificação de caracteres especificada por mb_regex_encoding() será usada como a codificação de caracteres para esta função.
This function is absolutely not multibyte-safe, it actually returns the position of the match as if the string was not multibyte.
The results of this function are exactly the same as if you were using preg_match_all with PREG_OFFSET_CAPTURE, even with the "unicode" flag it's simply NOT working
