Hello everyone, We are running koha 3.22.00 in a development VM and have a problem when making single character searches (i.e. searches that would normally return a lot of results). Oddly enough, our production koha which is on 3.02.02 does not suffer from the same issue (please see the relevant screenshots http://i.imgur.com/gFPtLBi.png http://i.imgur.com/ehJiURu.png). I followed the instructions in http://wiki.koha-community.org/wiki/Troubleshooting_Zebra and confirmed that the Zebra daemon does indeed return a result set when making a single character search (by issuing the "f α" command for example). So, I think the actual problem must lie with one of the Perl scripts that process the data fed back from Zebra/MySQL. How do we figure out which Perl script is choking on invalid UTF8 data? Is there a way to find which biblios/authorities contain invalid characters and to correct them? Thanks in advance for your help. Kind regards, Andreas
