Given that PETSCII is mostly ASCII, especially in text mode (assuming
you are doing a case insensitive Forth, like most Forth systems
around), I would just go with PETSCII, and would not expect many
problems from it. One exception is the absence of the characters {,
|, }, so you will have to choose some other characters (maybe those
that are at the place of {,|,} (123-125) if you want to implement the
new Forth-2012 locals syntax.

The C standard in its lack of definition is not a good standard to
follow. Standardizing ASCII allows to write such things as DIGIT
efficiently (and that will work just as well for PETSCII). I don't
think that there are many programs where the differences between
PETSCII and ASCII make a difference. Given that ASCII was the Forth
standard character set at least since 1994, when the Commodore
machines were more common than today, and IIRC nobody reported that as
a problem before 2016, I expect that it is not a big issue.
