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).
