I was just updating my HHVM patch to match your PHP implementation and
an issue came up.  The following code, which is valid in PHP5:

<?php
echo json_decode("\"ma\u00F1ana\"");

Will throw a fatal compiler error as "\u00F1" is an invalid unicode
escape sequence.  Since this represents an unnecessary BC break, I'd
like to propose the error handling be modified to match \x, which is
to say: Pass the value through unmodified.
