Certain characters not working on Czech QWERTY keyboard

[lahodaj]

Some characters, like '{' cannot be typed (and a bit surprisingly not even pasted) on Czech QWERTY keyboard. These characters are input using AltGr+Shift. Looking at the code here:

jline3/terminal/src/main/java/org/jline/terminal/impl/AbstractWindowsTerminal.java

Line 253 in 92a63e1

&& (controlKeyState & (RIGHT_ALT_PRESSED | LEFT_ALT_PRESSED | RIGHT_CTRL_PRESSED | LEFT_CTRL_PRESSED | SHIFT_PRESSED))

the code tries to detect AltGr, but it also checks that Shift is not pressed, so doing AltGr+Shift+{ is failing the check, and the character is not typed. If I remove the | SHIFT_PRESSED from the test, I can type the characters fine.

Is there a need for the test to include Shift? Will removing the Shift check break something?

Thanks!

I don't really see any problem in removing the check for the SHIFT key. Would you mind raising a PR for that ?
