[CWB] unicode problems with Greek and OCS

Tue Mar 10 12:31:02 CET 2015

Dear List,
so my second problem, this time with Ancient Greek. I cannot easily 
reproduce this with a 2-line corpus, because I don't know where the 
culprit is. I am posting the CWB Output instead, maybe this is already 
enough.

What I am trying to do: I am trying to align three documents, one Greek 
and two Slavic texts, using the aligVerse structural element. The two 
Slavic ones align fine, the Greek gives me the following error:

Again, I would be very thankful for help.

Best!
