Avoiding this problem in the future would be nice, but I already have this
character in my wiki, and I need to get rid of it. I don't know how it got
there, but more importantly, I need to find it, so I can remove it. With no
XAR export, we can't do our planned transision from an Oracle to a
PostgreSQL database.

As for the discussion on markmail.org – I have registered there, but I
can't find anything on the webpage that allows me to take part in the
discussion.

Cheers,
Peter
