I am not sure because both Unicode (e.g. http://kn.wikipedia.org) and 
Baraha/Nudi (e.g. online dictionary at http://kannadakasturi.com) are in use 
today. Teachers are also Government employees and use Nudi for departmental 
communications. Recent versions of Nudi are Unicode friendly and some versions 
run in Wine so old documents can be exported in UTF-8. The quality of GTK and 
Qt rendering engines have improved to a level where Linux/UTF-8 can be used 
for regular school work. We offer all options to the teachers and let them make 
their choices.

Attached picture shows the rendering in different fonts (FreeSans falls back to 
proprietary font). I had to increase my default font from 8pt to 9pt for a 
legible screenshot. Still the double subscript in 2nd glyph in first line in 
Kedage is barely readable. Only Lohit rendered Za correctly.
