Not that Python also respects a BOM in a UTF-8 file, treating the BOM as
flagging the file as being UTF-8.
"In addition, if the first bytes of the file are the UTF-8 byte-order
mark ('\xef\xbb\xbf'), the declared file encoding is UTF-8."
IMO we should do the same. If there's no explicit encoding declaration,
treat it as UTF-8 if there's a BOM and as the platform's local character
encoding otherwise.
