title: Enable Unicode Syntax in cabal
body: <p>I want to enabled Unicode syntax(UnicodeSyntax extension, base-unicode-symbols package and the containers-unicode-symbols). I don't want to enable per file, that is far too tedious.
  How do I enable all three in this .cabal file?</p>

  <p>This is 2013 and I want to use Unicode, not ASCII. </p>
