Re: [STUMP] UTF8 related bug

[Vladimir Sedach]

You can check which encoding system Emacs uses for a particular buffer
by doing C-h C Ret
(http://www.delorie.com/gnu/docs/emacs/emacs_220.html). It looks like
the shell is doing the "right" thing by displaying the '?'

Looking quickly at the backtrace, it looks like the place to fix the
crash in stumpwm is utf8-to-string in wrapper.lisp:212

The utf-8 encoding/decoding functions right now are pretty ugly and
have a bunch of implementation-dependent stuff in them. Replacing
those with either flexi-streams or babel is going to cut out a lot of
the code, provide more portability, and most important give a uniform
error interface. Now it's just a matter of doing it.
