BTW, I cannot reproduce that issue.
calibre is working fine on my systems
Comment by Archan Paul (archan.paul) - Tuesday, 24 January 2012, 12:37 GMT
As suggested by the upstream maintainer, following solves the problem.
LANG=en_US.UTF-8 calibre
Comment by Giovanni Scafora (giovanni) - Tuesday, 24 January 2012, 12:38 GMT
echo $LANG
what do it returns?
Comment by Archan Paul (archan.paul) - Tuesday, 24 January 2012, 12:39 GMT
I have updated /etc/rc.conf with following and now calibre works without problem.
LOCALE=en_US.UTF-8
Comment by Giovanni Scafora (giovanni) - Tuesday, 24 January 2012, 12:40 GMT
Maybe you have to set your LANG in /etc/rc.conf or elsewhere if you are using systemd.
Comment by Giovanni Scafora (giovanni) - Tuesday, 24 January 2012, 12:41 GMT
OK, then I can close this bugreport.
