Converts a Number or String to a single-character String.
char() converts numbers to their single-character string representations.
The parameter, n, is the value to convert. If a number is passed, as in char(65), the corresponding single-character string is returned. If a string is passed, as in char('65'), the string is converted to an integer (whole number) and the corresponding single-character string is returned. If an array is passed, as in char([65, 66, 67]), an array of single-character strings is returned.
See MDN for more information about conversions.
