Yes, Dinesh ji!
Ramabanam mullai may be written as
இராமபாணம் முல்லை.
Although '
இ' is prefixed in the Tamil version of 'Ramabanam', it is not usually transcribed as 'I-ramabanam'.
The name 'irampanam', which you mentioned in your first email had 'p'-anam instead of 'b'-anam changing the meaning from arrow ('banam',
பாணம்) to drink ('panam'
பானம்).
