How do you define ``support''?
If you mean software-level support, vim supports UTF-16, firefox
supports UTF-16/UTF-32, perl supports UTF-16/UTF-32, etc.
If you mean system-level support, there are two cases:
1. The system internal text representation is still in UTF-8, just add
support for terminal, stdin/stdout/stderr, etc. I think it's not so
hard (I might be
wrong because I don't know terminal at all) but I don't see any reason to set
locale to UTF-16 or UTF-32.
2. The system internal text representation is changed to UTF-16 or UTF-32.
This is another story and I have no comment on it.

Windows is another case. Windows use Unicode, but not in cmd.exe.
The cmd.exe is localized program thus the language used in cmd.exe is
depended on the language version of your windows. For example,
traditional chinese version of windows use CP950 as localized character
set, it is almost the same as zh_TW.Big5.
In cmd.exe, you cannot display two language (Chinese and icelandic for
example) at the same time because the Unicode is not supported here.
