Hello, is there any update?


We made some improvements to the API for this issue, but there is still one character that is incorrect. This needs more investigation and as soon as the ticket is completely resolved, we will share updates with you. Please give us some time.

We apologize for the inconvenience.

Could you please provide any ETA for the fix? We need to communicate this to our customers as this is a blocking issue for projects to go into production (as there is no workaround).

We further tried to resolve the issue but could not find the font information for the particular char “√”. We are afraid that we would not be able to fix this issue in near future. However, you will surely be notified as soon as we have additional updates to share.
