How to convert font

I am wanting to add a customized font with support from 0-9, A-Z and a-z. I am using littlevgl v5.3. Using the online converter, I am unable to specify min. unicode less than 32. I would ideally need support from 30-7A. Can you please help me?

I’d recommend upgrading to 6.0 if you are still starting your project.

30-7A are hexadecimal numbers. 32 is decimal. 0x30 = 48

Why not try typing characters directly on the next line?
