I found this font: https://font.download/font/dicey which has pips, etc, but when I loaded it I got all sorts of errors about Null Reference Exceptions if I try to add it to the Face Template window, generally like the error below: 
I could add the font to a face using "G-K" for 1 pip to 5 pips, but "L" (6 pips) threw the above error. If it can be made to work, this font could be added as an alternative default (it contains lots of pip variants), it might solve many problems. Otherwise I might try adding an image to a face instead of a font.
