This is very arguable.  Yes, it looks very wrong (which is one reason
why the whole concept of a global language environment disgusts me),
but I always have to do this by hand because inserting Unicode files
will give the wrong answer in Japanese buffers unless you force the
environment (specifically the Unicode precedence list) to Japanese.

What goes wrong if you have a Japanese language environment in a
non-Japanese buffer?
