hi ,
i really appreciate your fantastic work, i have a question is there a future plan to add support for math writing expressions , maybe this link help https://fonts.google.com/noto/specimen/Noto+Sans+Math, i don't know how it can be used , or is there any support for latex expression ... directly edited in blender , maybe i ask so much , thank you again

@hamza-el-barmaki - is there a future plan to add support for math writing expressions , maybe this link help https://fonts.google.com/noto/specimen/Noto+Sans+Math

That font will be distributed with Blender for version 3.4 as part of this: D15235: BLF: New Font Stack for Better Language Coverage

With the above we will have very good coverage of all the math and other symbols defined in Unicode (Noto Sans Symbols and Symbols2 is also included).

But this just means that we can output these symbols (even if the user changes the UI font). Composing them in any special way, like with Latex, isn't a part of this though. Although I can't think of any use case for Latex, I have no doubt that we will find interesting uses for these characters in the future.

cool your the best, i have a question, is there fonts as single-line font ?are they many ?
it well be interesting to convert them to Gpencil and add a build modifier for animation stuff (Single line font are better for that purpose), also play with other Gpencil modifiers.
i currently found a generator of single line font but it would be good to have them included in blender , https://www.templatemaker.nl/singlelinetext/
