passpie init: UnicodeEncodeError: 'ascii' codec can't encode character

[jbd]

Hello,

I'm trying to use passpie on my debian testing and it seems that I cannot use a passphrase with a "é" in it:

$ python --version
Python 2.7.9
$ virtualenv passpie
$ source passpie/bin/activate
(passpie)$ pip install --upgrade https://github.com/marcwebbie/passpie/tarball/master
(passpie)$ which passpie
/home/jbd/tmp/passpie/bin/passpie

Try to use a passphrase with some accentued characters in it does not work:

(passpie)$ passpie init
Passphrase: 
Repeat for confirmation:

Hello @jbd

Thanks for opening the issue. Just as another example to reproduce:

passpie -D /tmp/passpie init --passphrase é
