Avro makes instant messaging in Bengali child’s play. MSN Messenger (I have tested Windows Messenger Live) and Trillian works great with Bangla text. You can simultaneously key in text in both English and Bengali – changing the input language seamlessly at the press of F12 hotkey.
It has not been possibe to write Banlga in Yahoo Messenger directly. But can be achieved indirectly through use of Avro’s ‘Through clipboard’ mode — just remember not to use the right ‘shift’ key while typing in clipboard mode.
