Add a New Character in existing font

Hello, I am using TextMeshPro, and I want to add an ellipsis symbol(...) to an existing font. But I did not find any success in adding a new character using the font asset creator. Following is the link for the font-https://www.dafont.com/tovari-sans.font.

 

You are unable to add the Ellipsis character because it is not present in that font file as seen below.



A few options to handle this would be to (1) use from free font editor tool to add an ellipsis character to the font file. (2) find another font that has all the characters you need. (3) find another font that has a similar style / design and the ellipsis character and assign this other font as fallback to this primary font.
