Linux seems to support UTF-8-only pretty strongly: http://yarchive.net/comp/linux/utf8.html
(message from Sun, 15 Feb 2004 02:42:45 GMT).
And I completely agree.
If it's ok to kill iocharset!=utf8 I'll propose a series of 3 patches (killing iocharset!=utf8,
extending utf16toutf8/utf8toutf16 for unaligned input, changing UDF code to use common functions)
