Reply To: Certain text getting jumbled after running a script

It’s hard to see exactly what’s happening as the forum software has converted the (Oriya?) characters to ???? question marks.

A couple of thoughts –
1. Have you checked “missing glyph protection”?
2. You said of those two fonts that you are using: “author of one is retired and other is a free one”. I would suspect something not totally correct in the font, which causes problems for InDesign, but is accepted by other programs, perhaps?

U200C = ZWNJ – presumably you’re trying to *prevent* a ligature/conjunct there.
There’s a mention of ZWNJ problems in Oriya on a google groups forum here: https://groups.google.com/forum/#!topic/oriya_it/k6ysvNZOLMg

I have to sympathise – those legacy Indic scripts are a real nightmare to deal with.
Good luck,
Chris.
