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.
