Tkinter and astral characters (was: Decoding bytes to text strings in Python 2)

Tkinter in recent versions of Python can handle astral characters, at least
back to Python 3.8, the oldest I have on my Windows PC.

I just tried modifying
https://docs.python.org/3/library/tkinter.html#a-hello-world-program
to display "Hello World \N{ROCKET}" instead (Python 3.10.12 as included
with Ubuntu 22.04). I don't get a warning or error, but the emoji isn't
displayed either.

I suspect that the default font doesn't include emojis and Tk isn't
smart enough to fall back to a different font (unlike xfce4-terminal
which shows the emoji just fine).
