Description
int 
iconv_strlen ( string str [, string charset] )
      Returns the character count of str.
    
      In contrast to strlen(),
      iconv_strlen() counts the occurrences of characters
      in the given byte sequence str on the basis of
      the specified character set, the result of which is not necessarily
      identical to the length of the string in byte.
    
      If charset parameter is omitted,
      str is assumed to be encoded in
      iconv.internal_charset.
    
      See also strlen() and mb_strlen().
