I installed Libreoffice via Software Station to GhostBSD 14.1-STABLE. For some reason it does not accept input in Japanese characters (alphanumeric English is fine).

Is there some way to install anversion of LibreOffice which allows input in Japanese? Thank you!

There might be some missing font. I will look and comeback with an answer.

Is your keyboard set to input Japanese characters?

Japanese input works for me. Did you install ja-ibus-anthy?
My keyboard is set to Japanese input

Sorry alexintokyo I forgot to mention that there is some configuring needed for Japanese input in Libreoffice

I'm using ibus-anthy for my Japanese input and I had to put some entries in my .profile file in my home folder to get Japanese input to work.
Japanese input won't work in Libreofiice because in is a QT program and ibus-anthy won't work in QT programs without some configuring.

In your .profile file put these lines

export GTK_IM_MODULE=ibus
export QT_IM_MODULE=ibus
export XMODIFIERS=@im=ibus

Then you'll probably need to log out and login or reboot for these changes to work. Hope this helps
