httpd and locale

Hi,

Is it possible to serve files with non ASCII UTF-8 charaters in their
names with httpd? I have tried to start httpd like this:

$ env LC_CTYPE=en_US.UTF-8 httpd -d

But, I always get a 404 error on such files. Am I missing something?
Or maybe this behaviour is on purpose?

Thanks.
