# asciiValue The ASCII encoding value of this character, if it is an ASCII character. ``` var asciiValue: UInt8? { get } ``` ## Discussion ``` let chars: [Character] = ["a", " ", "™"] for ch in chars { print(ch, "-->", ch.asciiValue) } // Prints: // a --> Optional(97) // --> Optional(32) // ™ --> nil ``` A character with the value “\r\n” (CR-LF) is normalized to “\n” (LF) and has an `asciiValue` property equal to 10. ``` let cr = "\r" as Character // cr.asciiValue == 13 let lf = "\n" as Character // lf.asciiValue == 10 let crlf = "\r\n" as Character // crlf.asciiValue == 10 ``` --- Copyright © 2026 Apple Inc.
