Yes it is. I used LC_ALL here because that was the only one that made "svn
info" switch to English when default locale is set to "fr_FR.utf8".

% LC_ALL=C svn info

I had not tested what non-ASCII encoding became, and you're right that the
shell can't handle utf-8 anymore.

% LC_ALL=C svn log

With a "franÃois" repository and LC_ALL=C:
% vcs_info command ; vcs_info_lastmsg                          
$vcs_info_msg_0_: "svn:(franfranÃois37ois:1) "

The other solution would be to use the line numbers to fetch the data from "svn
