Comment:
`Data.ByteString.Lazy.hGetContents` calls `hIsEOF` which calls
`hLookAhead`, and `hLookAhead` reads the next `Char` from the `Handle`,
which does Unicode decoding. Putting `stdin` into binary mode fixes the
problem.
After giving this a bit of thought, I think the best solution is to make
`hIsEOF` not do any decoding, so I'll look into doing that.
