Yes, and no. There's basically zero chance that we'll ever allow these
ecodings as server-side encodings, because they aren't strict ASCII
supersets (that is, not all bytes of a multibyte character are
individually distinguishable from an ASCII character). The amount of
work involved, and the ongoing hazard of security bugs that would ensue,
is just prohibitive.
We do however support them as client-side encodings with automatic
translation to and from Unicode on the server.
