Most current POSIX systems use UTF-8 encoding by default. AFAIK This is not the case under Windows. > I probably wrote my code relying in undefined behaviors... You generally need to tell Emacs what's the (expected) encoding of a process's output. Emacs generally assumes it's "the system's default" if not, but that's bound to be wrong every once in a while. You can do that by let-binding `coding-system-for-read`, `process-coding-system-alist`, or `default-process-coding-system` around the call to `call-process`. For async processes you can do it more directly by passing a `:coding` arg to to `make-process`. Stefan
