I suggest using msvcrt.getwch instead of msvcrt.getch. Both functions
are limited to the basic multilingual plane (BMP, i.e. U+0000 --
U+FFFF), but getch is additionally limited to the console input
codepage. In Windows, getpass.getpass is based on msvcrt.getwch and
msvcrt.putwch.

If you use getch and need the full BMP range, you can temporarily
change the console input codepage to UTF-8 (65001). It's a multibyte
encoding (i.e. 1-3 bytes per BMP code), so the initial getch call has
to be followed by a loop that calls it again while the sequence can't
be decoded and kbhit() is true.
