[c#] How to write Unicode characters to the console?

I was wondering if it was possible, in a console application, to write characters like ? using .NET. When I try to write this character, the console outputs a question mark.

This works for me:

Console.OutputEncoding = System.Text.Encoding.Default;

To display some of the symbols, it's required to set Command Prompt's font to Lucida Console:

1. Open Command Prompt;

2. Right click on the top bar of the Command Prompt;

3. Click Properties;

4. If the font is set to Raster Fonts, change it to Lucida Console.

Besides Console.OutputEncoding = System.Text.Encoding.UTF8;

for some characters you need to install extra fonts (ie. Chinese).

In Windows 10 first go to Region & language settings and install support for required language:

After that you can go to Command Prompt Proporties (or Defaults if you like) and choose some font that supports your language (like KaiTi in Chinese case):

Now you are set to go:

Console.OutputEncoding Property

Note that successfully displaying Unicode characters to the console requires the following:

• The console must use a TrueType font, such as Lucida Console or Consolas, to display characters.

I found some elegant solution on MSDN

System.Console.Write('\uXXXX') //XXXX is hex Unicode for character

This simple program writes ? right on the screen.

using System;

public class Test
{
    public static void Main()
    {
        Console.Write('\u2103'); //? character code
    }
}
