init subcommand fails: LookupError: unknown encoding: charset

[Fabio Quintilii]

Hallo,

I'm testing pybabel on Pythonanywhere and when I run the init subcommand it fails with "LookupError: unknown encoding: charset" exception.

I use python2.7 version, but pybabel runs under python3.5.

The issue was reported in the topic https://groups.google.com/forum/#!topic/python-babel/lT-005ICU1M, but It was not clear for me.

Can someone give me any suggestion?

Regards, Fabio
