The Unicode FAQ from unicode.org says that "the unmarked form (UTF-16, UTF-32)
uses big-endian byte serialization by default, but may include a byte order
mark at the beginning to indicate the actual byte serialization used." So,
I guess the strictly correct thing to do for UTF-16 would be to
* check for a BOM.
* if it exists
* if it is U+FFFE, modify the port encoding to UTF-16-LE
* if it is U+FEFF, leave the port encoding as UTF-16
* discard the BOM
* else, leave the port-encoding to UTF-16
and similarly for UTF-32.
Thanks,
- Mike
