unknown encoding

[Adam Mercer]

Hi

I've just install bzr-0.14 on Mac OS X and whenever I call bzr at get
the following warning displayed:

bzr: warning: unknown encoding . Continuing with ascii encoding.

I've tried looking for whats causing this or a solution but can't find
any relevant documentation.  Does anyone know whats going on here and
how I can fix it? Or any documentation that discusses this?

Cheers

Adam
