I can reproduce the panic on both urxvt and uxterm.

On urxvt, GHCi works correctly with putStrLn "£". On uxterm, it just
prints a blank space.

I can type the GBP sign into both terminals.

Could it be a terminfo problem of some sort? It seems suspicious that
there is a difference between terminals.
