UnicodeEncodeError from `bzr help` when localisation is enabled

[Dmitry Shachnev]

Bzr crashed when I ran "bzr help push".

Traceback (most recent call last):

Status changed to 'Confirmed' because the bug affects multiple users.

[Martin Packman (gz)]

I only trigger this when piping the output or similar so the stdout stream has no encoding specified, are there other ways too?

[Dmitry Shachnev (mitya57)]

No, for me it crashes only when I pipe it (for example, to less).

[IWATA Hidetaka (hid-iwata)]

AFAICS::
   Windows 7 + Python 2.7.2 => `bzr help` works.
   Windows 7 + Python 2.6.6 => `bzr help` crashes even when no pipe specified.

[Daniel Cordeiro (dcordeiro)]

I can reproduce it if I run, for example:
$ LC_ALL=C bzr help update

[Dmitry Shachnev (mitya57)]

Quantal still has 2.5.0, so changing the status back until 2.5.1 is uploaded.
