Depending on your webserver, Unicode characters should be possible in
URLs. Certainly some non-7-bit characters can be represented in URLs
with % encoding.

On my Apache system, for example, the string:

áüÜć

in latin-1 encoding is represented in a URL as:

%c3%a1%c3%bc%c3%9c%c4%87

If that same byte sequence is decoded as UTF-8 instead, it is:

áüÜć

(a-acute u-umlaut U-umlaut c-acute)

In other words, you can send an arbitrary byte sequence in a URL with %
escapes. How that byte sequence is decoded into a sequence of characters
depends on your web server and its configuration - or, if the web server
sends the % encoded URL directly to your client, on how your client
chooses to interpret it.

The main trouble will be ensuring that clients and the server agree on
the character encoding used in the URL.
