What do you mean by "should"?

Current implementation uses terminal encoding, in this case it will be 
cp850. If terminal is not available, then there will be used default 
user encoding, in this case it will be cp1252.

Here is the list of supported encodings (ANSI and OEM):

As you see there is no UTF-8 encoding in any form, so user unable to 
switch the terminal encoding to UTF-8. Only to cp1252, because it's the 
best match for cp850 (cp850 is OEM, cp1252 is ANSI encoding).

To switch encoding of the terminal user can use chcp command.
When this command invoked without arguments it will print current codepage.

E.g. on my machine with Russian settings:

C:\>chcp
Active code page: 866

C:\>chcp 1251

C:\>chcp
Active code page: 1251

Yes, PLEASE. I think it should be global option, available to all 
commands. E.g.

bzr --encoding=utf-8 log
