The char data type represents a 16-bit unicode character.
To declare a variable of type char and assign it a value, simply put the value within single quotes, like this:

char c = 'Z';

The character data type can also be assigned escape values. An escape value always begins with a backslash.
For example carriage return and linefeed are two characters that can be escaped with:

char carriageReturn = '\r';

char newLine = '\n';

Escape sequences can also be done by specifying a Unicode escape sequence. Such a sequence starts with \u followed by a four digit hexadecimal value (\uXXXX).

Useful escape sequences:

\" - Double quote

\' - Single quote

\b - Backspace

\t - Horizontal tab

\n - Newline

\f - Form feed

\r - Carriage return

\\ - Backslash
