I can reproduce this with GNU Emacs 21.3.1.

It seems to me that either the function
`utf-16-le-pre-write-conversion' is missing or the line should be
removed from `utf-16.el' (same for -be-, probably):

     (pre-write-conversion . utf-16-le-pre-write-conversion)

I did a quick test with the dummy function "(defun
utf-16-le-pre-write-conversion (from to))": With this defun, I could
read Markus Kuhn's UTF-8 demo file[1] in Emacs 21.3, save it as
`utf-16-le'.  The result is readable in Emacs 21.3.50 (CVS HEAD).

But I'm not at all an expert in this, so it probably better to report
this as a bug: `M-x report-emacs RET'.

Bye, Reiner.
