[Koha] Search in intranet with non-ASCII-characters

[Beda Szukics]

Hi all

Since I upgraded to 3.20 I have a very strange search problem.

In the intranet interface searches with a non-ASCII-character show no
results.

In the opac interface the results are there.

For example:

"Schärer" results in an error:

No results match your search for 'kw,wrdl: Sch�rer' in ...

"Scherer" shows some results (in my case 236 items).

In /var/log/koha/kb/intranet-error.log I see:

[Sat Jun 20 20:34:43.521663 2015] [cgi:error] [pid 20806] [client
192.168.1.52:57404] AH01215: [Sat Jun 20 20:34:43 2015] search.pl:
CGI::param called in list context from package main line 421, this can
lead to vulnerabilities. See the warning in "Fetching the value or

436., referer:

However there is also an entry for "Scherer":

[Sat Jun 20 20:37:13.234366 2015] [cgi:error] [pid 20899] [client
192.168.1.52:59580] AH01215: [Sat Jun 20 20:37:13 2015] search.pl:

What's wrong? Any suggestions?
