(Apache) Can I match UTF8 characters in rewriting rules?

Question

I know that it is possible to create links where UTF8 characters are encoded, but is it possible to actually match these characters in rewriting rules? Example: just rewrite the static page in utf8 Cyrillic Russian text to some other page.

Answer 1

Yes, it is possible:

RewriteRule ^de/b\xC3\xA4ume$ en/trees [L]

This will match /de/bäumeand rewrite it on /en/trees.
