Or ... anything: > > (python-shell-buffer-substring 2 (point) nil) > => "# -*- coding: utf-8 -*- > > 1+2" I have to admit that I don't understand the reason for the coding cookie at all -- we bind coding-system-for-write to utf-8 before writing the temp file anyway, and on the Python side, we specify the coding system explicitly there, too. But in case it does have an effect, I haven't removed it altogether, but instead made the C-c C-e command avoid outputting it, which fixes the problem. C-M-x, probably a more important command, is not affected by the cookie one way or another (since it's just side-effecting), so I've left it alone there. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
