UTF-16

If I am not mistaken, we have reached a consensus on the 
charset "utf-16".  What will happen next?

-----------------------------------------------------------
We propose to register UTF-16 as a charset in IANA.

UTF-16 generators MUST send in big-endian byte order and must
begin with the zero width non breaking space (also called Byte
Order Mark or BOM) (0xFEFF).

NOTE: Some implementations that do not conform to this
specification have occasionally sent data in little-endian byte
order. When they do this, they commonly precede the data with the
BOM.  Thus, an UTF-16 parser encountering the code 0xFFFE as the
first character of a purported UTF-16 stream may safely assume
that he has encountered a nonconformant data source.  If the BOM
is absent, there is no way to 100% reliably detect little-endian
data that does not use the BOM.

This character set is not permitted for use with MIME text/* media
types.  However, the MIME-like mechanism of HTTP may use this
character set for text/*, since this mechanism is exempt from the
restrictions on the text top-level type (see section 19.4.1 of
HTTP 1.1 [RFC-2068]).

Charset name(s): UTF-16

Published specification(s): 

UTF-16 as a Character Encoding Scheme is defined in Appendix C.3
of [UNICODE] and Amendment 1 of [ISO-10646].

The Coded Character Set that UTF-16 refers to is the same version
of ISO/IEC 10646-1 and Unicode that the charset "UTF-8" refers to.
