TLatex Subscripts & Superscripts

I am trying to make a simple TLatex for Oxygen-16, but the subscript and superscript are covering each other unless a character is typed prior to them. Should I be using some sort of blank character before the subscript and superscript?

TLatex t; t.DrawLatex(0.1,0.1,"^{16}_{8}O");


BTW. do search for the “{}” sting in

Ahh, I didn’t read down far enough. Thanks.
