The Windows console shell is an 8-bit entity. That means you only have
256 characters available at any given time, similar to they way
non-Unicode strings work in Python 2. The "code page" determines which
256 you are using. You can type "chcp" to see the current code page.
By default, you get code page 437, which derived from the original IBM
PC character ROMs. You simply cannot type or display characters that
are not in the current code page.
Using msvcrt.getchw does not convert the console to a Unicode entity.
It merely means the characters you DO get are represented in Unicode.
The Windows console theoretically supports a UTF-8 code page (chcp
65001), and it does fix many of these problems, but there are some
console apps that won't like it.
It is 16 bits per character
There may be some confusion in that each code page is 256 codes
