/**
* Unicode aware replacement for strlen(). Returns the number

* multibyte characters with a single byte equivalent
* utf8_decode() converts characters that are not in ISO-8859-1
* to '?', which, for the purpose of counting, is alright - It's
* much faster than iconv_strlen
* Note: this function does not count bad UTF-8 bytes in the string
* - these are simply ignored
