[Bf-committers] Python console IO encoding: PYTHONIOENCODING envvar

[Bastien Montagne]

Well, in the bug report error comes from a print in addon_utils.py... 
Here is a patch (small wrapper around print that sets 'file' kwarg to 
sys.stderr) that fixes the issue, at least for me (tested with an ascii 
console): http://www.pasteall.org/45600/diff
