9tna is this an abreviation for Yndia ?

I have seen this abbrev. Otna or something that looks like a curvy 9tna .. It was seen in my recent post and again in another post following a persons name..What is this .. isnt there a book published that has abbreviations listed ?

I am convinced that the 9t( the t is elevated and small was actually part of the Y so the Abrreviation is Yna.. Yndia
