@ahsaniqbalsidiqui thank you :wink:

@ahsaniqbalsidiqui any update ?


After an initial investigation, we found the issue is caused by special layout of some characters. I am afraid, we need more time to investigate it and then we could give a plan to fix it.

A rough eta to fix the issue is before the end of Q2, 2021, For your information, there are lots of work needed to be done/implemented. So, 40 days time is too short to accomplish it. However, we will try our level best to fix it as soon as possible.

Thanx for your response, but really its tooo urgent and important to be fixed within that 40days …or we have to find another tool … because we have a deadline.

Regards :wink:

@Amjad_Sahi or maybe can u give me a workaround for this issue?


We are sorry but there is no workaround for it. Currently, we are investigating the HarfBuzzSharp (NuGet Gallery | HarfBuzzSharp 7.3.0) lib to check whether it can be used to help to fix the issue. Once we have an update on it, we will let you know.

@Amjad_Sahi Thanx for your response. :slight_smile:

We can not fix the issue in 40 days (from 2 Jan, 2021) even using HarfBuzzSharp (NuGet Gallery | HarfBuzzSharp 7.3.0) lib. We need to change our data model a lot if we use the HarfBuzzSharp lib.

@ahsaniqbalsidiqui ok Thanx.

Please notify me when an update is available for that Issue.



Sure, we will notify you once an update is available on your issue.

The progress of this ticket is blocked due to difficulty for using HarfBuzzSharp lib into our code.
Currently, we can’t give a possible ETA. We will update you if we have some news.
