Indian Language Support in Google Docs & Google Apps
Google Docs in Google Apps now supports all popular local languages of India including Hindi, Tamil, Telugu, Gujarati, Kannada, Malayalam, Bengali, Marathi and Oriya.
To switch the interface from English to an Indian language, go to settings and choose your desired language from the drop down.
Other than creating documents, spreadsheets and presentations, Google Docs also has an in-built spell checker for each of the localized Indian languages. via

बहुत अच्छा प्रयास है.
Amit,
are you sure that the spell checker is working for indic languages other than hindi. I dont see that working for telugu atleast. Though I could manage to see the docs interface in that language
Does it allow typing these new languages also? I don’t see any Indian fonts.
Didn’t see any punjabi, did I miss it?
