You can print special characters on the console in two easy steps:

1. Change the console properties with a right-click on the Console (You can change the Defaults as well) to enable Unicode-friendly font (the default is Raster Fonts):

2. Enable Unicode for the Console by adjusting its output encoding Prefer UTF8 (Unicode):

Console.OutputEncoding = Encoding.UTF8;

Here is the whole cyrillic alphabet:

using System;
using System.Text;
 
class Alphabet
{
    static void Main()
    {
        Console.OutputEncoding = Encoding.UTF8;
        char a1 = 'А';
        char a2 = 'Б';
        char a3 = 'В';
        char a4 = 'Г';
        char a5 = 'Д';
        char a6 = 'Е';
        char a7 = 'Ё';
        char a8 = 'Ж';
        char a9 = 'З';
        char a10 = 'И';
        char a11 = 'Й';
        char a12 = 'К';
        char a13 = 'Л';
        char a14 = 'М';
        char a15 = 'Н';
        char a16 = 'О';
        char a17 = 'П';
        char a18 = 'Р';
        char a19 = 'С';
        char a20 = 'Т';
        char a21 = 'У';
        char a22 = 'Ф';
        char a23 = 'Х';
        char a24 = 'Ц';
        char a25 = 'Ч';
        char a26 = 'Ш';
        char a27 = 'Щ';
        char a28 = 'Ъ';
        char a29 = 'Ы';
        char a30 = 'Ь';
        char a31 = 'Э';
        char a32 = 'Ю';
        char a33 = 'Я';
        Console.WriteLine("Cyrillic Alpahbet: {0}, {1}, {2}, {3}, {4}, {5}, {6}, {7}, {8}, {9}, {10}, {11}, {12}, {13}, {14}, {15}, {16}, {17}, {18}, {19}, {20}, {21}, {22}, {23}, {24}, {25}, {26}, {27}, {28}, {29}, {30}, {31}, {32}", a1, a2, a3, a4, a5, a6, a7, a8, a9, a10, a11, a12, a13, a14, a15, a16, a17, a18, a19, a20, a21, a22, a23, a24, a25, a26, a27, a28, a29, a30, a31, a32, a33);
    }
}

OUTPUT:

You can also add this:

Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;

or

Thread.CurrentThread.CurrentCulture = new CultureInfo(ru-RU);

before

Console.OutputEncoding = Encoding.UTF8;
