What happened to unicode?

I've been using the unicode branch of cvs.  After updating today, it no
longer builds, telling me that the unicode branch is merged into mainline
and I should do cvs update -A.  I did.

Now I'm looking at a file and emacs doesn't display unicode characters.
Any ideas?

Here's the file:
