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
% LC_MESSAGES=C LANG=C LC_CTYPE=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

So setting LC_ALL=C globally is indeed a bad idea. But why not just locally in
VCS_INFO_get_data_svn? I don't think that behavior would hurt much vcs_info.
The only problem I can think of is when the repository name is not un ASCII,
and doing this really calls for troubles ;-)
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
