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.

Solution 1

It's likely that your output encoding is set to ASCII. Try using this before sending output:

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

(MSDN link to supporting documentation.)

And here's a little console test app you may find handy:


using System;
using System.Text;

public static class ConsoleOutputTest {
    public static void Main() {
        Console.OutputEncoding = System.Text.Encoding.UTF8;
        for (var i = 0; i <= 1000; i++) {
            if (i % 50 == 0) { // break every 50 chars


imports Microsoft.VisualBasic
imports System

public module ConsoleOutputTest 
    Sub Main()
        Console.OutputEncoding = System.Text.Encoding.UTF8
        dim i as integer
        for i = 0 to 1000
            if i mod 50 = 0 'break every 50 chars 
            end if
    End Sub
end module

It's also possible that your choice of Console font does not support that particular character. Click on the Windows Tool-bar Menu (icon like C:.) and select Properties -> Font. Try some other fonts to see if they display your character properly:

Solution 2

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

Solution 3

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:

Solution 4

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.

Solution 5

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.
