HTTP and unicode

Where can i expect unicode strings when writing a webserver? The standard says HTTP headers are UTF-8, but now there are unicode domain names. Of course the Content-type can be anything other than utf8, but that isn't the main problem

My bad!
So if I get this correctly, my language C implements ascii. latin-1 is an extension to ascii, adding 128 new characters.

However, resource locators in http headers could still be in unicode!
