Hey g00r00, I was wondering if you knew of a reason that embedded python3 would
not be able to print extended characters... e.g. if I do:

"write(chr(177))" it will print garbage....

mps files work fine, so I know the system has to be at least partly configured
correctly. And, other than that python3 works as expected.

My setup is:
Mystic 1.12 A48
Rpi 4 4GB
Raspian Bullseye

Let me know if this is something that sounds familiar. Thanks!

-Clive

I can somewhat confirm this; however, it's worth noting that since Python 3
uses unicode by default chr() doesn't behave the same as in Python 2. chr()
will output the unicode character of that number.

In a terminal you could use something like b'xc0'.decode('cp437') (sorry that's
just the hex code for the character I was testing with) to output an ANSI
character. But this also doesn't seem to output as expected with mpy.

.... My software never has bugs. It just develops random features...

Hey Travis, That's a very good point and would tend to confirm my suspicion.
Thanks, for the response!
