Idiom #47 Extract string suffix

Create string t consisting in the 5 last characters of string s.
Make sure that multibyte characters are properly handled.

The end of the string s
t = s[-5..-1]
(let [t (clojure.string/join (take-last 5 s))])
(def t 
  (when (string? s)
    (let [from (-> s (count) (- 5) (max 0))]
      (subs s from))))

PROGRAM-ID. suffix.
