I did not find any information on how to input indic languages (Bengali, Hindi, etc, languages spoken and written in the Indian subcontinent) in Archlinux/Archlabslinux using Openbox, hence I thought it might be useful for some how I figured it out after searching the
ibus and localisation support pages and digging through the internet. Anyway, the steps are
sudo pacman -S ttf-indic-otf
sudo pacman -S ibus m17n-db ibus-m17n
/etc/locale.genfile to uncomment your language (I used bn_IN.UTF-8), and then run
ibus-setupand indicate the key bindings, edit the
~/.zshrcfiles if you must.
