 The code below segfaults on a variety of platforms and GHC versions - I've
 tried 7.4.1 and 7.6.1, on Windows and Linux.

 It seems to be related to (a) the specific choice of UTF8 - doesn't happen
 with UTF16 or UTF32 etc and (b) having the invalid byte sequence at the
 end of the thing being decoded.

 {{{
 import qualified Data.ByteString as B
 import System.IO

 tempFile = "temp"

 main = do
utf8Ignore <- mkTextEncoding "UTF8//IGNORE"
B.writeFile tempFile (B.pack [128])
h <- openFile tempFile ReadMode
hSetEncoding h utf8Ignore
hGetContents h >>= putStrLn
 }}}
