Hi Milan,

thank you from the prompt answer!

Yes, this was with CLISP.

This is on a computer with no Lisp system whatsoever previously

I just said "apt-get install stumpwm" and `apt-get' installed `CLISP'
along.  I was a little surprised, since I was expecting 'SBCL' to be
installed, but decided to play the naïve user who just wants to try

It's really four chars there: a backslash followed by the number 366.
The buffer coding system is UTF-8.

In retrospect I think that `\366' is not correct, now that my `~/.emacs'
is UTF encoded.  It's a reminiscence of the time the encoding was

Anyway, my opinion is that `stumpwm' (or `CLISP') should not crash.
Not showing the char or cutting the window title off would be OK IMHO.

If `stumpwm' plays better with SBCL maybe the order of the dependencies
could be changed so that SBCL is prefered over CLISP.  Now (Version
2:0.9.8-1) it reads:

    Depends: clisp-module-clx | cl-clx-sbcl | cmucl-source, cl-ppcre
