No. :-)

if you 'print' it you get:

print 'å'
= putStrLn (show 'å')
= putStrLn "\229"

this has nothing to do with 8-bit IO. It's just what 'show' does for

If you..
putStrLn "å"
then you do get the low 8 bits being printed. But that's not what is
going on above.

import qualified Codec.Binary.UTF8.String as UTF8
putStrLn (UTF8.encodeString "å")

or just:

import qualified System.IO.UTF8
UTF8.putStrLn "å"
