Use Google Indic Transliteration API to allow users to transliterate english typed...

This is available only on the masthead search box in the OPAC.

User has to enter a word in english and press space or return to transliterate the word. The destination language can be selected from a drop down list. User can temporarily turn on/off the feature by using "ctrl +g".

A system preference - GoogleIndicTransliteration can be used to turn on this feature.
