key 5 on the numeric pad does not print as 5

[mglt]

Description Pressing the key 5 on the num pad returns the following object: {'vk': 65437, 'char': None, 'is_dead': False, 'combining': None, '_symbol': None}

I would have expected an object with its char set to '5'. I do not know if this is a bug or something I am not using correctly.

Other keys works fine for example typing 1 returns the following object: {'vk': None, 'char': '1', 'is_dead': False, 'combining': None, '_symbol': None}

Platform and pynput version Linux 5.4.0-136-generic #153-Ubuntu, pynput Version: 1.7.6 as well as the one of the git

To Reproduce Running keyboard-test.py results in:

$ python3 keyboard-test.py Press esc to exit =< Key.enter => <65437>5 =< <65437> => '1' 1=< '1'

Can confirm I see this too. Numlock is enabled. I have debug script in one of my projects and noticed that it produces the output <65437> for numpad 5:

# This script just prints what each key is called

import sys, termios, time

from pynput import keyboard

run = True

def _onPress(key):
    print(key)

def _onRelease(key):
    global run
    if key == keyboard.Key.esc:
        run = False
        return False

# Modified version of `enable_echo` found at https://blog.hartwork.org/posts/disabling-terminal-echo-in-python/
def setEcho(value):
    iflag, oflag, cflag, lflag, ispeed, ospeed, cc = termios.tcgetattr(sys.stdin)

    if value: lflag |= termios.ECHO
    else: lflag &= ~termios.ECHO

    termios.tcsetattr(
        sys.stdin,
        termios.TCSANOW,
        [iflag, oflag, cflag, lflag, ispeed, ospeed, cc]
    )

def clearStdin():
    termios.tcflush(sys.stdin, termios.TCIFLUSH)
    # sys.stdin.flush()   # Doesn't seem to do anything

if __name__ == '__main__':
    print('Press keys to see what pynput shows them as. Hit Esc to exit.')
    try:
        setEcho(False)
        listener = keyboard.Listener(on_press=_onPress, on_release=_onRelease)
        listener.start()
        while run: time.sleep(0.1)
    finally:
        listener.stop()
        print('Listener stopped')
        clearStdin()
        setEcho(True)
        print('Echo reenabled')

I am on Ubuntu 20.04 x86_64, using pynput 1.7.6 with the xorg backend. All other numpad numbers work fine. If it's relevant my keyboard layout is standard US QWERTY.

Same problem on my side (With Manjaro). Saw similar post on stack overflow with same behavior: LINK

I wonder does anyone see this on Windows or is it a keycode/map issue specific to Linux?

[mglt]

I am only using Linux, so I cannot tell if Windows has the same issue or not. Yours, Daniel

Thank you for your report.

I can confirm that I observe this behaviour as well. It appears that display.keycode_to_keysym returns KP_Begin for numpad 5. There is code to correct these values when numlock is active, but KP_Begin was not present in the list of codes to translate. By applying the fix below I can get numpad 5 to work on my system.
