GHCi produces a panic on printing and escaped GBP sign, and won't print gbp sign either

[yb2]

Prelude> putStrLn "£" � Prelude> putStrLn "\£" ghc: panic! (the 'impossible' happened)

(GHC version 6.10.4 for i386-unknown-linux):

charType: '\163'

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug --- I've also compiled a bit of code with GHC that can't output GBP symbol either. --- Tested with Hugs for comparison,

Hugs> putStrLn "£" £

Hugs> putStrLn "\£" ERROR - Illegal character escape sequence "\�" ---

I tested the outputting (not the escaping) in roxterm and xterm, and both output the question mark in a diamond symbol.

6.12.1 will have Unicode support in the IO library which mostly fixes this problem. The rest is fixed by #3398.
