what is ASCII code for right filled arrow " ►"

Question

I am trying to print right filled arrow ► in C# this is I tried

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

but it is showing the output as ? (question mark) I have gone through this question also but the it doesn't seem to work. Can you help me with correct ASCII code which shows the correct output?

Console uses another code page than a windows text box. Just hit Win+R and type "charmap" there you get character tables in windows. — Grisgram, Jan 09 '20 at 07:16
It's not in ASCII. It's unicode codepoint U+25BA. So `"\u25ba"` would work. — Sweeper, Jan 09 '20 at 07:16
@Grisgram Well, that depends on the encoding of the console... — Sweeper, Jan 09 '20 at 07:17

You can easily convert char to int and thus obtain its code:

  char arrow = '►'; // Copy + Paste from the question

  Console.Write($"{arrow} : {(int)arrow} : \\u{(int)arrow:X4}";);

Outcome:

  ► : 9658 : \u25BA

and that's why you can put

  char arrow = '\u25BA';

Change the console output encoding before printing:

Console.OutputEncoding = Encoding.Unicode;
Console.WriteLine((char)9658);
// or just
//Console.WriteLine('►');

The black filled arrow is not included in the ascii charset. You need to use unicode.

In your example:

string myString = "\u25BA";
Console.WriteLine(myString);

You also need to be aware that the font you use can display the specific unicode character. As far as i know the default console font does not support it.
