I built this font for my GDW/T2K stuff. It is built off the standards from the late 80s.

Key commands to get the proper units
https://games.juhlin.com/font/
It is a little clumsy to use. But I have used in doc,ai,ps,visio, etc.
Generally you do the size of a unit first then type. To copy one for reuse you need to select two characters( one right further than you would expect) as technically the unit is a character and a backspace.
Never really made it totally user friendly (it was for generating table top game counters and dynamic map symbols) but if it is on any use I can try to help you figure it out.
