What does the program print?

SWIFT

let word = "résumé"
print(word.count, word.utf8.count)

6 8

Expecting 6 6: treating é as one byte like a Latin letter. In UTF-8 it takes two bytes, so the two é add two extra bytes to utf8.count.
Expecting 8 8: thinking count counts bytes, as string length does in some languages. In Swift count counts characters, and bytes are counted by utf8.count.
