--- Comment #25 from Zdenek Dohnal zdohnal@redhat.com --- CUPS takes system locale (from /etc/locale.conf) and LANG variable too.
I was able to reproduce with steps:
1) localectl set-local LANG=C 2) export LANG=C 3) /usr/lib/cups/filter/texttopaps 1 root '' 1 '' <Greta's file>
When I change system locale and env variable LANG to C.UTF-8, the file goes through the filter without error.
