Last sprint I've talked with Martin about adding global command-line 
option --encoding to force specific encoding of output. I don't remember 
the resume on this.

*Python* does not understand it. Bazaar is Python application and it 
heavily relies on what Python as platform provides.

Very strange. Really.

This error comes from Python. It has no knowledge about cp65001. Maybe 
bzr can add alias for this encoding to treat it as utf-8. Although in my 
experiments it's not possible to print anything correctly from python to 
console with such encoding. Again, Python as platform.

Yep :-/
