[Neobrahmigp] Query on confusable composite characters

Hello Akshat and the NBGP members, In our recent discussions on confusable composite characters, we have noticed that the confusion is only prominent across certain fonts and not with all universally. I have attached a few samples where the strings and the respective fonts are highlighted in yellow. The question is - are we considering font specific issues here? Are there any fonts being considered to be used as default ones to display Devanagari text on the browser's address bar? Regards, Bal Krishna
