If you force djvused to emit UTF-8 encoded text, you need to bind
coding-system-for-read to 'utf-8, to make sure Emacs decodes that
correctly.  I'm guessing your locale uses UTF-8 by default, which is
why it worked for you.

Please also add a comment there explaining what the -u switch does and
why we use it there.

Thanks.
