You can enter Unicode characters directly into your source code using the editor in Visual Studio. These characters will be stored and intepreted correctly, if contained in a comment or a string literal. (Unicode characters are not used in any C# keywords).
You can also enter a hex code for the Unicode character, rather than entering the character directly. (E.g. By copying/pasting it or entering from a keyboard that includes the character)
