Like Java, a char in C# is a 16-bit Unicode character instead of the traditional 8-bit ASCII character of older programming languages. Table 9.5 shows escape the sequences supported by C# which can be used in character assignments or within string literals.
|Escape sequence||Character represented||Comments|
|\'||single quote||Same as in Java|
|\a||alert (beep sound)||No such escape sequence in Java – For example, System.Console.WriteLine("\a "); causes a beep.|
|\b||backspace||Same as in Java|
|\v||vertical tab||No such escape sequence in Java|
