[AUCTeX] Non-ASCII LaTeX labels (was Re: Headache: filenames with Umlaut under Windows, backward search gives error)

I guess you are using RefTeX.  Have you tried the variable
`reftex-label-illegal-re'?  It might be good for you to customize it to
"[^-a-zA-Z0-9_+=:;,.[:multibyte:]]".

(That value may be too loose, however.  I don't know what range of
unicode characters are allowed for LaTeX labels.)
