Thanks for narrowing it down...  I'm aware that that syntax still needs
some work on it, it's only half-converted to supporting non-ASCII
characters, so it's probably not surprising this sort of thing happens.
The problem is the way characters are stored is quite specific to a
single-byte representation; I've made it so that it can be extended to
multibyte/wide characters, but it hasn't been.

I'm not going to get it properly converted before the next release since
it's a big job (I started it once back in June and got bogged down).  When
I get a chance, I'll look and see if there's any thing obvious I can do
with Meta-encoded characters that will work round the problem for now.

Until then you should be able to get away with the old syntax,

zstyle ':completion:*' matcher-list 'm:{a-z}={A-Z}'

since before I finish the job it won't actually handle non-ASCII character
conversions properly anyway.

I will document my way round this as follows...

 The pattern var(tpat) may also be one or two stars, `tt(*)' or
 `tt(**)'. This means that the pattern on the command line can match
