`bzr send` failed with UnicodeEncodeError

[Alexander Belchenko]

I want to send the patch to my co-worker. Last log message contains russian text. Because `bzr send --mail-to` pass last log message as subject line to mail client it fails on win32:

bzr: ERROR: exceptions.UnicodeEncodeError: 'ascii' codec can't encode characters in position 132-140: ordinal not in range(128)

I don't use Linux to send patches so I don't know is this bug related to Linux. So I'll try to fix it for Windows only. If someone else encounter this bug on Linux -- it should be filed as another bug.
