Subject: JSON.parse and unicode escape?

The documentation for the ruby JSON classes (http://json.rubyforge.org/)
implies that it handles unicode escaping fine. But I'm having trouble
with parsing JSON with a unicode escape sequence in it.  I am using the
'ext' parser (JSON::Ext::Parser) not the 'pure' parser. version 1.1.2,
which appears to still be the latest.

Here is some test JSON, that's actually an excerpt from some JSON
returned to me by a third party web service. Finally boiled it down to
the simplest demonstration case. I saved it in a file, but here's what's
in the text file:

=====
{ "key": 'something \x26 more' }
=====

I believe that is valid json, containing an escaped unicode char?  But
JSON.parse on that string throws, complaining:

JSON::ParserError: unexpected token at '{ "summary": ' \u0026 ' }


I have verified it is the /x26 that's doing it. It doesn't like \x
escaped unicode.

Am I doing something wrong? Is the JSON I am receiving from the third
party bad somehow? This is such a widely used library that I'd be
surprised if it's broken and can't parse input including unicode escape
sequences... but that's what it looks like to me. Feedback?
