{{{
 Prelude> "Hel\x6c000000000000000 World"
 <interactive>:1:7: lexical error in string/character literal at character
 'c'
 Prelude> "Hel\x6c0000000000000000 World"
 "Hel\NUL World"
 }}}

 Two bugs really: the first error message gives a strange location, and the
 second example is probably the result of an overflow somewhere.
