I have tested this (I was the reporter of the Bangla character issue).
The visual appearance looks much better with the HarfBuzz shaping factory, but now instead the Unicode table is broken, i.e. you cannot copy/paste from the PDF or index the content the way that you can without the HarfBuzz stuff.
Is there any solution for this? (verified in v. 21.5)
Please try the latest version of Aspose.Words for .NET 21.9 and let us know how it goes on your side. If you still face problem, please ZIP and attach your input, problematic output and expected output documents. We will investigate the issue and provide you more information on it.
first I was going to write it doesnt work in 21.9 but I can see it actually does, I was fooled by a ligature that we couldn’t present.
Thanks for the support.
