How can i use special symbols from charmap in console application?

Question

I'm trying to enter a special character, but the app still displays a message «Wrong password!» If anyone knows what my mistake is, I will be glad if you point it out. Thanks in advance.

Special character i use: ☺ (U+263A)

Console.WriteLine("Enter a password:");

var pass = Console.ReadLine();

var key = '\u263a'.ToString();

while (pass != key)
{
    if (pass != key)
    {
        Console.WriteLine("Wrong password!");
        pass = Console.ReadLine();    
    }
    else
    {
        break;
    }
}
Console.WriteLine("Info: test 123");

Console.ReadKey();

upd. Screenshot 1: variable "pass" in debug

Screenshot 2: variable "key" in debug

@LasseV.Karlsen The string contains "\u0001" instead of "\u263a" — Euxinus, Jan 03 '22 at 13:23
I am not surprised, the console is somewhat lacking in terms of handling unicode. You can get some support but I don't think it supports it fully. — Lasse V. Karlsen, Jan 03 '22 at 13:33
@LasseV.Karlsen Thanks. I solved the problem by changing the variable string to "char" and "readline" to "readkey(true)". I also removed the "key" variable and just added the desired symbol to the "if" condition. — Euxinus, Jan 03 '22 at 13:51

try to decode it to UTF-8

Console.WriteLine("Enter a password:");

Console.InputEncoding = System.Text.Encoding.UTF8;
var pass = Console.ReadLine();

var key = '\u263a'.ToString();

while (pass != key)
{
    if (pass != key)
    {
        Console.WriteLine("Wrong password!");
        Console.InputEncoding = System.Text.Encoding.UTF8;
        pass = Console.ReadLine();    
    }
    else
    {
        break;
    }
}
Console.WriteLine("Info: test 123");

Console.ReadKey();

Unfortunately, this method did not work. By the way, I noticed the variable "pass" in debug: After entering a character in the console, it accepts the string "\u0001" instead of "\u263a" – Euxinus Jan 03 '22 at 13:01
Probably `System.Text.Encoding.Unicode` instead. – Phil1970 Jan 03 '22 at 14:17

Just put this

Console.InputEncoding = Encoding.GetEncoding(1200);

at the top of the program

You should explain what is `1200`. Why not `System.Text.Encoding.Unicode`? – Phil1970 Jan 03 '22 at 14:12
