Are you saying that my workaround for the svn2html.pl script (used by
the website scripts to convert Subversion's XML output to HTML)
prevented you from adding Unicode chars to the commit message? Unlikely,
as that script is run as a post-commit hook.

The only side-effect of the workaround is that you will see strange
characters instead of the correct Unicode char on the website's SVN log
pages. But IMHO, that's better than no svn HTML logs at all.

I think you will agree with me that we should first find out _how_ an
invalid char managed to get into the Subversion commit message and how
can we prevent this from happening again, before letting svn2html.pl
trust that "svn log --xml" is outputting correct XML.

IIRC, we are using fsfs as backend now, so do you know whether is it
possible to use this same aproach for that backend too? Also, is it
garanteed that the "broken" commit message was not duplicated somewhere
(e.g. with branching, merges etc.)?
