Inconsistent key event of "shifted" characters between Windows and Linux

[ndtoan96]

Describe the bug Inconsistent key event of "shifted" characters between Windows and Linux

To Reproduce Steps to reproduce the behavior:

1. Run the official example of crossterm key event: https://docs.rs/crossterm/latest/crossterm/event/index.html
2. On US layout keyboard, press Shift + a then Shift + /
3. See the difference in below table

Key	Windows	Linux
Shift + a	Char('A') + SHIFT	Char('A') + SHIFT
Shift + /	Char('?') + SHIFT	Char('?') + 0x0

Expected behavior

1. I expect that the same key press will produce the same key event regardless of OS
2. I expect in the case of Linux, when pressing Shift + key, the behavior is consistent. You can see in the table above, I got a SHIFT with Shift + a but I got 0x0 with Shift + /.

OS Windows and Kali Linux

Terminal/Console

• On Windows: Windows Terminal
• On Kali Linux: the default terminal
