I am planning to migrate to Lucidchart from Omnigraffle and stuck  with a very crucial bug of unicode typing in Lucidchart.

When I use unicode Sinhala font with an unicode keyboard (in Mac OS) Fonts not render/working properly. 

As an example ; if I type “මිසි ත්‍රිකෝනි විව් ටිට් ක්කිකු නින්නු තිත්තු විවුන්‍ර” ” using unicode font from Google “NotoSansSinhala” ; 

  1. it works correctly in this messaging window as well as any other web application
  2. It worked correctly in the Omnigraffle as in the below image
  1. However, it renders as below in the Lucichart

    Can you please let me know how to fix this?

Hi ​@colD,

Thank you for posting in the Lucid Community! In order to take a closer look at the issue you’re experiencing, could you follow the troubleshooting steps below?

  • Try opening your document in a private or incognito window to help us narrow down the potential cause? For help with opening an incognito window, please see this community post.
  • Try connecting to a different network or disconnecting from your VPN (if applicable)? Sometimes account performance issues can be related to internet security/speed or browser issues. These steps will help us eliminate that possibility.

If those don’t resolve the problem, can you please send the following information so I can take a closer look?

  • A screenshot of the issue.

  • A screenshot of the associated Javascript Console output after reproducing the issue. You can open your Javascript Console by pressing Ctrl+Shift+J (if your computer is a Windows/Linux) OR Cmd+Opt+J (if your computer is a Mac).

Thanks in advance for your help and patience!
