Comment:

 iconv and mb_convert_encoding behave identically.  Tested with various
 valid and invalid byte sequences.  These functions do not check for code
 point validity, but they do a good job of stripping individual bytes that
 fail to decode.

 Trivially noted disagreement with preg_match using invalid code points
 0xD800 and 0x140000.
