Pynput - no capital letters

[jmair]

Is there a known issues with Windows 10 to where it doesn't recognize characters modified by shift or Caps Lock?
It does record the key event of the shift press.

Anyone know if I'm missing something ?

from pynput.keyboard import Listener

def look_for_key(key):
        
    letter = str(key)
    letter = letter.replace("'", "")
        
    if letter == 'Key.esc':
        return False
    
    print(letter)


with Listener(on_press = look_for_key) as l:
    l.join()
