Looks like some unmeta() calls are missing.  One of them is below —
wasn't hard to find; I just opened bin_zcompile() and searched for the
error message — but with that patch I get 'b\xc3\x83\x81r.zwc' rather
than 'bár.zwc', so I guess a few more calls are needed.  I won't be
tracking them down.

(Not going to commit this patch, either.  It's incomplete and lacks a
test case.)
