Bug#754179: stumpwm crashes when window title contains national chars

[Emilio Lopes]

Package: stumpwm
Version: 2:0.9.8-1
Severity: important

Dear Maintainer,

the subject says it all.  In my case I have the following in my ~/.emacs:

    (setq-default frame-title-format (list "" "Emacs Macht Alle
Computer Sch\366n"))

Eval this in an Emacs buffer an watch stumpwm crash:

    *** - CONVERT-STRING-FROM-BYTES: Invalid byte sequence #xF6 #x6E
#x00 #xA0 in CHARSET:UTF-8 conversion

This is possibly related to other bugs of the kind, like #509583.

Thank you very much!

 Emilio
