What is the difference between the Unified Text Engine and the Universal Text Engine? Does the latter use HarfBuzz? helpx.adobe.com/after-effects/…

I would guess Photoshop has such a menu, to enable the Unified Text Engine (which is using HB) helpx.adobe.com/photoshop/usin…

To get correct shaping with a Kannada nukta with InDesign, I needed to enable HarfBuzz (HB) community.adobe.com/t5/indesign-di… It would be great if HB could be enabled with a menu item, rather than a script. Can I expect to see this in InDesign 2023?

@lianghai @NorbertOnEarth @TiroTypeworks While I can see all the properties I need for a character from my spreadsheet, I see now that I would have to use filters to see all the characters for a specific script. scripts.sil.org/ExcelUnicodeDa…

@TiroTypeworks I am curious what font is shown. The font I used supports 3 options for the nukta 1133C, 1133B, and 0323 trying to find something that works.

@TiroTypeworks @parthakr I found that I need to get InDesign to redraw the text to have the changed shaper take effect. Redrawing the text is also needed if you install a new version of a font, and restart InDesign. I force the text to be redrawn by changing the size (and then changing the size back).

@TiroTypeworks @parthakr I use the same setting. I actually use two different files, HarfbuzzOverrideOn.js and HarfbuzzOverrideOff.js so that I can toggle between the two within InDesign without having to edit a text file.

@TiroTypeworks @parthakr At least for Tamil script with InDesign 2022, enabling HarfBuzz via Javascript does make a difference. The examples below have a nukta, which has made shaping difficult. With HarfBuzz the left vowels get re-ordered and the nukta gets positioned.
