Incorrect event.text for punctuation characters for Windows

For Windows event.text inside Keys.onPressed contains text "1" for key combination "Ctrl+Shift+1", and text "!" for key combinations "Shift+1" and "Alt+1".

For Linux all of three key combinations "Ctrl+Shift+1", "Shift+1" and "Alt+1" produce event.text with value "!".
