When running ikiwiki-3.20140102-1.mga4 on Mageia Linux x86-64 4/Cauldron with perl-5.18.1-3.mga4 , I am getting this error after I try to preview a page that contains unicode, at least in firefox-24.2.0-2.mga4 (note that I added "use Carp::Always;" to Ikiwiki.pm to get the stack trace):

Error: Cannot decode string with wide characters at /usr/lib/perl5/vendor_perl/5.18.1/x86_64-linux-thread-multi/Encode.pm line 215.

I have upgraded the ikiwiki instance using "ikiwiki -setup" and am running ikiwiki.cgi on a local Apache server.

Can anyone shed any light on this problem and guide me what I need to do to fix it?
