[Lispweb] utf-8 manipulations

[Frédéric Gobry]

Hi,

I'm working on my 1st lisp-based web application (I'm a lisp newcomer
too :-)). It's based on Araneida, and runs in sbcl (0.8.16 from debian
sarge, no unicode support).

In my app, users can provide names for certain pages, say:

 Page accentuée
 
which should give birth to an url that matches the name as
much as possible but remains readable, say:

 page-accentuee

I get the user input as an utf-8 string. Is there a library to help me
processing the raw name into the url-clean version, or should I write
both an utf-8 parser and the equivalent of python's translate () method?

Any general advice on that topic is welcome, as I don't have much
experience with lisp.

Frédéric
