Configure Firefox browser to view regional language properly

Koha can handle records in Indian regional languages well. We need to install Indic Fonts packages to display Indian languages. Even though Indic Fonts available, Firefox browser does not display the record details properly. Here is the solution to fix the regional language view problem in Koha server and client computers using Ubuntu Linux.

1. Install Indic Fonts package

sudo apt-get update

sudo apt-get install fonts-indic

2. Adjust Firefox Font settings

Firefox > Edit > Preferences

Search for "Content" through search box. Select Advanced option

Select Malayalam Language and set a font.

Zebra configuration for regional language searching

I have tried these steps on Koha 3.12.7 and Ubuntu 12.04 LTS.
Koha installation method based on Debian packages.

Open following file,  
Applications > Accessories > Terminal

sudo mousepad /etc/koha/zebradb/etc/default.idx

Find the line "charmap word-phrase-utf.chr" and comment it by inserting a # symbol. The same line appeared in next paragraph too, do the same.

Add following line below the commented lines, 
icuchain words-icu.xml

Rebuild zebra
sudo koha-rebuild-zebra -v -f library
