subprocess.Popen with a unicode path

Question

I have a unicode filename that I would like to open. The following code:

cmd = u\'cmd /c \"C:\\\\Pok\\xe9mon.mp3\"\'
cmd = cmd.encode(\'utf-8\')
subprocess.P         


        

Answer 1

It looks like you're using Windows and Python 2.X. Use os.startfile:

>>> import os
>>> os.startfile(u'Pokémon.mp3')

Non-intuitively, getting the command shell to do the same thing is:

>>> import subprocess
>>> import locale
>>> subprocess.Popen(u'Pokémon.mp3'.encode(locale.getpreferredencoding()),shell=True)

On my system, the command shell (cmd.exe) encoding is cp437, but for Windows programs is cp1252. Popen wanted shell commands encoded as cp1252. This seems like a bug, and it also seems fixed in Python 3.X:

>>> import subprocess
>>> subprocess.Popen('Pokémon.mp3',shell=True)
