Comment 1 for bug 1068936

I can't reproduce this error locally even with:

   LANG=pt_BR.UTF-8 bzr send --help

which emits:

bzr: warning: unsupported locale setting
  bzr could not set the application locale.
  Although this should be no problem for bzr itself, it might
  cause problems with some plugins. To investigate the issue,
  look at the output of the locale(1p) tool.

because I don't have the pt_BR locale installed.

ERROR:

bzr: ERROR: exceptions.UnicodeEncodeError: 'ascii' codec can't encode characters in position 116-117: ordinal not in range(128)

should indicate that bzr cannot find the right encoding to use and falls back to ascii, so there is probably something weird in your setup that bzr fails to recognize, not sure what though :-/
