$ python3
Fatal Python error: Py_Initialize: can't initialize sys standard streams
LookupError: unknown encoding:
Abort trap
There is a "fixed" issue in the bug tracker but the problem persists in my installation.
A quick workaround is to set LC_CTYPE properly. Check how it is now with the locale command (mine was UTF-8)
$ export LC_CTYPE=en_US.UTF-8
Add this to your ~/.profile.
