Documentation:
Coding system to use with system messages.

It is totally nonintuitive that that variable, documented as this, 
should have an influence on X11 decoding.

It's obviously set up automatically to be so in ISO-8859-1 locales! 
Try launching emacs with LC_ALL=ru_RU.KOI8-R, you'll see it 
automatically sets locale-coding-system to cyrillic-koi8.

Note also that you don't need set-keyboard-coding-system to decode 
iso-latin-1 or cyrillic-koi8. It's just done automatically by Emacs.

I don't think it's a MULE issue, really, but rather a weirdness in 
the routines decoding X11 keyboard input. To me, that's how the thing 
works:

X11 -keysyms-> Xlib -UTF-8-> Emacs X11 interface -> extra keyboard 
decoding (Mule)
and the problem is in the Emacs/X11 interface.
