[Haskell-cafe] question about show

[k at ioctl.it]

Okay, it makes somewhat more sense now after reading that thread. But
technically, why does



show "ü"



not handle Unicode? Isn't the internal representation of [Char]
actually still Unicode, as per



[1]http://hackage.haskell.org/package/base-4.6.0.1/docs/Data-Char.html



Thanks!

"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
