However, it will not display characters such as:

I verified that my font contains the higher-code-point characters. I can see them in the font (using “Font Book”), but they don’t display in Unity. I need to be able to display the higher-code-point for my application. Thank you for your help!

Could your raise a bug so we have this in our database to look at.

I reported the issue using the Unity Editor: Help → Report a Bug.

Looking forward to it being fixed in a future release. Thank you.

Any update on when this bug will be fixed? Thank you!

It looks like fixing this issue requires updating our internal font rendering backend (I don’t think unity has ever supported this). Because of this it’s unlikely the issue will be fixed before we rewrite text rendering.
