Suppose there's a subdirectory named |`MÜNCHEN`| in the current
directory, then tab-completion won't recognize this directory, when |`cd
münchen`|+ [tab] is given.

I noticed this behavior when attempting to |cd| the given directory
(with tab autocomletion), and while doing the same with `|rm -r`|.

I assume, *it's a zsh-wide issue due to broken case-insensitive matching
umlauts.*

I'd like to provide some patch, but I was unable to figure out, where
the bug is caused.

Thanks,
Luis

Version of zsh?
Operating system?
Locale settings?

How are you enabling case-insensitive matching?  That is, are you
using a matcher-list specification?  With or without NO_CASE_GLOB?

matchers only support single-byte characters, comp.h says:
/*
 * For now this just handles single-byte characters.
 * TODO: this will change.
 */
and the manpage agrees:
       `m:{[:lower:]}={[:upper:]}'.   Although the matching system
does not yet han‐
       dle multibyte characters, this is likely to be a future
extension,  at  which
       point  this  syntax  will handle arbitrary alphabets; hence
this form, rather
       than the use of explicit ranges, is the recommended  form.   In
 other  cases

The UTF-8 representations of «ü» and «Ü» differ by exactly one byte,
though.  I wonder what would happen if that byte (0x9C v. 0xBC) were
declared equivalent…
