Internally the paths in bazaar are unicode (not __encoded__). 
The problem in the function _show_diff_trees() is that they mixes userdata 
(which is already __encoded__) and the paths which aren't __encoded__. I 
don't know if it is the only one case.

Because I use this function inside in my web interface (webserve) I suggest to 
pass another parameters to the function: the encoding of the unicode data 
(the filepath).

So, for an internal use (as webserve), this function encodes the data as utf8; 
for the external use (the bzr diff command for example) the encoding is 
the "user's encoding".

I am guessing how this function can _now_ work on non utf8 environment (ie 
windows). I have two hypotesis:
1) it doesn't work and display an utf8 encoded stream in a non utf8 
environment
2) it works, because on the stdout the utf8 encoded stream is converted to the 
local encoding
