2 Examples top

  • user> (reverse "foo")
    "oof"
  • ;; clojure.string/reverse correctly treats UTF-16 surrogate pairs
    ;; as a unit, and does not reverse the 2 Java chars of the pair.  Good!
    user=> (def s "smily \ud83d\ude03.")
    #'user/s
    user=> (def x (str/reverse s))
    #'user/x
    user=> (map #(format "%04X" (int %)) s)
    ("0073" "006D" "0069" "006C" "0079" "0020" "D83D" "DE03" "002E")
    user=> (map #(format "%04X" (int %)) x)
    ("002E" "D83D" "DE03" "0020" "0079" "006C" "0069" "006D" "0073")
