`ord()` difference between V1 and V2

[microbit-carlos]

Originally reported in bbcmicrobit/micropython#775 and related to bbcmicrobit/micropython#774, but makes more sense in the V2 repo.

print("code point: {}".format(hex(ord("°"))))

In V1 we get the same as running the code in CPython:

code point: 0xb0

In V2:

TypeError: ord() expected a character, but string of length 2 found

Maybe setting the MICROPY_PY_BUILTINS_STR_UNICODE flag in the V2 build could help with this issue.

Yes, setting that flag fixes this. That should be set to match micro:bit v1.

Done in 60a991f

I also enabled frozenset which was missing compared to v1. See 4e9c550

Thanks Damien!
@microbit-matt-hillsdon we might need to add this to the micro:bit stubs.
