Does this happen with specific messages? Do you have a sample message 
for me? I don't see how Unicode could cause this.

I cannot reproduce this so far (see modified schema below). In a simple 
test I just get the desired results and no errors logged.

What errors do you see? I see only INFO entries in my 
/var/solr/logs/solr.log. Looks like Solr is pretty verbose by default 
(lots of INFO output), but there must be a way to reduce that.
