ASCII code for ► is \u25BA

I am trying to print the right filled arrow character () in C#, but when I run the following code it outputs a question mark (?) instead:

static void Main(string[] args) {
   Console.WriteLine((char)16);
}

I have already checked this Stack Overflow question, but it doesn’t seem to work. Can you help me find the correct ASCII code to get the desired output?

The right filled arrow character (►) has the ASCII code of 16. However, the console font used by the operating system may not support this character. To ensure that the character is displayed correctly, you can use the Unicode escape sequence \u25BA instead:

static void Main(string[] args) {
   Console.WriteLine("\u25BA");
}
