I can confirm that this bug is still present in Ubuntu 22.04 LTS. If i change my password in windows server to not contains any special characters, i can successfully create PPTP VPN connection. If i change password to contain character ä (U+00E4), VPN connection fails with "CHAP authentication failed". All other configurations and options remain the same.
