Closed luigy closed 5 years ago

luigy commented 6 years ago 
{-# LANGUAGE OverloadedStrings #-}
import qualified Data.JSString as JSString

main :: IO ()
main = do
  let txt = "\915929"
      len1 = JSString.foldr (\_ -> (+ 1)) 0 txt -- 1
      len2 = JSString.length txt -- 2
  print $ len1 == len2 -- False
