Characters

Characters are represented by the type Char. Character literals go in single quotes: '1'.

Special characters start from an escaping backslash \. The following escape sequences are supported:

• \t – tab

• \b – backspace

• \n – new line (LF)

• \r – carriage return (CR)

• \' – single quotation mark

• \" – double quotation mark

• \\ – backslash

• \$ – dollar sign

To encode any other character, use the Unicode escape sequence syntax: '\uFF00'.

fun main() {
//sampleStart
    val aChar: Char = 'a'
 
    println(aChar)
    println('\n') // Prints an extra newline character
    println('\uFF00')
//sampleEnd
}

If a value of character variable is a digit, you can explicitly convert it to an Int number using the digitToInt() function.
