Terry J. Reedy <tjre...@udel.edu> added the comment:
Terminal codepages are irrelevant in the IDLE tk based gui. The problem is
that windows codes astral chars as two surrogates. While tkinter can display
them, after recent changes to _tkinter, the text widget cannot handle then
properly when editing. This was explained in more detail on an earlier issue,
but I will have to check if there is already an issue for fixing it.
For editing, one should use unicode escapes, as in
>>> print('\U0001f60d')
😍
Python in a Windows console prints the surrogates separately.
and in IDLE, one will see a black-and_white version of the smiley.
