As far as I recall (and with a brief review of the thread I referenced
above to refresh my memory) svnmerge is, when reading the log messages
printed by svn, trying to use the same encoding as that used by svn to
output them. It does this by reading in the current default locale,
which is what I believe svn outputs, with the caveat below.

As per some comments in svnmerge.py there is one situation which isn't
currently handled: that is when log-encoding is specified in the svn
configuration. In that case, svnmerge.py's assumption of the log
encoding used by svn will probably be wrong. Is this the case for you
Benson?

If so, a patch is needed to svnmerge.py to handle this by reading the
svn configuration and checking for the log-encoding setting.

If not, then we need to investigate, in Benson's specific case, what
logic svn is using to determine the encoding of the log message output
-- then patch svnmerge.py to replicate that logic. Or alternatively
tell svnmerge.py to force svn to always output log messages in UTF-8
and set svnmerge.py to read in the same.

If the first approach is taken, Someone would likely need to check the
svn code or ask on the svn dev list. Daniel Shahaf on #svn was helpful
the last time around.

A new test case would also be helpful.

Cheers,
Raman
