utf-16-le-pre-write-conversion missing

utf-16-le-pre-write-conversion missing

[Dave Evans]

When set-buffer-file-coding-system is set to utf-16-le,
I get error
"symbol's function definition is void: utf-16-pre-write-conversion"
in the minibuffer when attempting to save a file.

Any idea where I can find this function?

Emacs 21.3.1 i386--freebsd

AFAIK, Emacs 21.3 does not support utf-16.  So it must be coming from
some kind of package, perhaps you installed Mule-UCS?

Alas, I don't have an Emacs 21.3 at the moment to check.  Please bear
with me if it is wrong.

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.

The etc/NEWS file says:

   ** UTF-16 coding systems are available, encoding the same characters
   as mule-utf-8.  Coding system `utf-16-le-dos' is useful as the value
   of `selection-coding-system' in MS Windows, allowing you to paste
   multilingual text from the clipboard.  Set it interactively with
   C-x RET x or in .emacs with `(set-selection-coding-system 'utf-16-le-dos)'.

I have tried using

   (set-selection-coding-system 'utf-16-le-dos)

but I only end up getting an error when I save files.
