[Koha-patches] [PATCH] Bug 15818 - OPAC search with utf-8 characters and without results generates encoding error

[Dobrica Pavlinusic]

When searching for something in OPAC which doesn't result in any results but have utf-8
characters in search string we get following encoding error:

Cannot decode string with wide characters at /usr/lib/i386-linux-gnu/perl5/5.20/Encode.pm line 215.

This is because we are trying to decode string which is allready correctly
marked as utf-8.

Test scenario:

1) enter search string with utf-8 characters in opac which doesn't
   return any results
2) verify that you get application error
3) apply this patch
4) re-run query and verify that errror is gone
