With readline 6.3 on Windows, you could type Alt 234 and it would produce
GREEK CAPITAL LETTER OMEGA U+03A9. However with readline 7.0 it yields nothing.

interactively.
They cannot be pasted either; pasting some words will remove all non ASCII
characters. I did a git bisect on the readline-7.0-testing branch and came up
with this:
