"Show" is for debug output. It's not a generic "to_string". See this thread [1] from last week for more info.

Hello!

 

I'm sure this has been answered many times before, but I can't find an

explanation for this behavior anywhere. The question I have is a general

one regarding 'show'. Why does

 

main = do

    putStrLn "ü"

 

➜  ~ runhaskell test.hs

ü

 

 

and:

 

main = do

    putStrLn $ show "ü"

 

➜  ~ runhaskell test.hs

"\252"

 

Thank you all for an enlightening answer already!

 

Best,

 

k
