Unicode uses two encoding forms: 8-bit and 16-bit, based on the data type of the data that is being that is being encoded. The default encoding form is 16-bit, where each character is 16 bits (2 bytes) wide. Sixteen-bit encoding form is usually shown as U+hhhh, where hhhh is the hexadecimal code point of the character.
To insert a Unicode character, type the character code, press ALT, and then press X. For example, to type a dollar symbol ($), type 0024, press ALT, and then press X. For more Unicode character codes, see Unicode character code charts by script.
Unicode supports more than a million code points, which are written with a "U" followed by a plus sign and the number in hex; for example, the word "Hello" is written U+0048 U+0065 U+006C U+006C U+006F (see hex chart). There are several formats for storing Unicode code points.
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:
C#
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++) {
Console.Write(Strings.ChrW(i));
if (i % 50 == 0) { // break every 50 chars
Console.WriteLine();
}
}
Console.ReadKey();
}
}
VB.NET
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
Console.Write(ChrW(i))
if i mod 50 = 0 'break every 50 chars
Console.WriteLine()
end if
next
Console.ReadKey()
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:
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
}
}

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.
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:
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:
Open Command Prompt;
Right click on the top bar of the Command Prompt;
Click Properties;
If the font is set to Raster Fonts, change it to Lucida Console.
