How are emoji flag characters represented in Swift strings?

Question

Like some other emoji characters, the U+1F1E9 U+1F1EA combination (German flag, 🇩🇪) is represented as a single character on screen although it is really two different Unicode character points combined. Is it represented as one or two different characters in Swift?

Answer 1

let flag = "\u{1f1e9}\u{1f1ea}"

then flag is 🇩🇪 .
