Add function to replace character in font library about pxt-max7219_8x8 HOT 3 CLOSED

You can "print" a custom character using one of the blocks. It will just be a mess to simply let you modify hidden global variables.

This works well in the MD_Parola Arduino library. We simply replace the "." and "1" characters and get exactly what we need.

I understand what you are trying to do. But this is not Arduino. I had to cut down some original functions so that this extension can run on micro:bit v1's smaller RAM, especially people (including STEM educators) would often run it with several other sensor extensions.

And like what I've said in your duplicated issue: the font is not monospaced (equal width fonts) in the first place. Changing only one character is an ugly, unnecessary inconsistency for all other users.
