The startup binary voor pyapp forces LC_CTYPE to en_US.UTF-8 during the call to Py_Initialize, and resets it to whatever it was before afterwards. This is primairly done to ensure a sane I/O encoding when using Python 3 (that is, for the '.UTF-8' bit). I can only test with 10.6 in a virtual machine, I should have some time later this week to do so (in particular to check what locale related environment variables are set automaticly there and to find why --emulate-shell-environmet doesn't pick those up). You can force the right settings by setting them yourself in your python script (os.environ['LC_CTYPE'] = 'fr_FR.UTF-8', etc., etc., before calling subprocess.Popen). That's suboptimal, but should at least give you a working program without changing all R scripts.
