This can be fixed by changing:\n\n``` ruby\n        # Escapes quotes within a quoted string.\n        def escape_quotes(str)\n          str.gsub(/\"/, '\\\\\"')\n        end\n\n        # Unescapes quotes within a quoted string\n        def unescape_quotes(str)\n          str.gsub(%r{\\\\}, '')\n        end\n```\n\nwith\n\n``` ruby\n        # Escapes quotes within a quoted string.\n        def escape_quotes(str)\n          String(str).gsub(/\"/, '\\\\\"')\n        end\n\n        # Unescapes quotes within a quoted string\n        def unescape_quotes(str)\n          String(str).gsub(%r{\\\\}, '')\n        end\n```\n\nBut I'm not totally confident I'm doing everything correctly. Totally willing to make the change, but I want to confirm that this is, indeed, unexpected behavior. At the very least, this seems to cause a 415 to be returned, even though I suspect it should return something in the 500-series (since this is a server-side problem).\n","author":{"url":"https://github.com/jfredett","@type":"Person","name":"jfredett"},"datePublished":"2014-10-30T15:24:34.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/201/webmachine-ruby/issues/201"}
