Here I am posting this Guide to viewing the fonts that you need.
I chose Hindi language and Mangal.ttf fonts.
Make sure you use TrueType fonts only.
And this method requires making CHANGES TO REGISTRY so i suggest that you USE AT YOU OWN RISK .
1. Full unlock ROM
2. WP7 root tools installed
3. Mangal.ttf font file that will be available on any computer windows 7 installed on it. Go to
control panel/font. Here you find mangal.ttf copy that file to anywhere and send it to your
phone. Mangal.ttf also available on internet download it to your phone.
1. Use WMDC to copy font to your phone at \Windows. http://forum.xda-developers.com/show....php?t=2691682
2. Open WP7 Root tools.
3. Open Registry editor go to local machine/system/GDI/font. Here create a new value and
give value name as mangal.ttf and give value data 1 and save it.
4. After doing all process Restart your phone and after that you will be able to view hindi
font on you wp7.
