如何在haskell中获取char的ascii值？以及如何将ascii值(65,让我们说)变成char(A)？

import Data.Char (ord)

main :: IO ()
main = do
  let char = 'A'
      asciiValue = ord char
  putStrLn $ "The ASCII value of " ++ [char] ++ " is " ++ show asciiValue

The ASCII value of A is 65

import Data.Char (chr)

main :: IO ()
main = do
  let asciiValue = 65
      char = chr asciiValue
  putStrLn $ "The character corresponding to ASCII value " ++ show asciiValue ++ " is " ++ [char]

The character corresponding to ASCII value 65 is A
