Font Support - Indian Languages

Mac OS X comes with default font support for Indian Languages(Hindi, Tamil, Telugu, Kannada,Oriya, Malayalam etc.,). However, it is restricted with default font styles that comes bridged with OS.

You can view these in in the system preferences - languages & text.

One way to enable creating documents in Indian languages is ,

1. Open System Preferences -> Languages & Text.
2. Go to "Input Sources" tab.
3. Choose the languages you want in the left pane.

This will add the language map to your keyboard layout. You should be able to view/edit documents in default Mac text applications.

However the real challenge is compatibility of various font styles for a single language. For example, Hindi font styles(Shusha, Kruti dev 010 etc., ), tamil(baamini, anjali etc.,). Viewing/editing documents containing such fonts created/edited in PC is very simple.

As by default, when you open such documents, applications like office for mac, Please follow the below steps,

1. Download the corresponding ttf files.
2. Put them in Users/<User account>/Library/Fonts.
3. Restart the application.
4. Open your document.
