-       It's not possible to type Ctrl+Space (aka ^@) into the CMD.EXE

-       processes that keystroke into an EOF event, even when we don't

-       Emacs users. One solution is to install the "Windows Terminal"
-       application from Microsoft Store, type Ctrl+Shift+, to get its
-       settings.json file opened, and add this code to its "actions":
-

-       Its not possible to configure Windows Terminal to output our
-       control codes. The workaround is to encode control sequences
-       using the "Control Pictures" UNICODE plane, which we'll then
-       translate back from UTF-8 glyphs, into actual control codes.
-
-       Another option Windows users can consider, particularly when
-       using CMD.EXE is installing Microsoft PowerTools whech makes
-       it possible to remap keys then configure ncurses to use them
