+Subject: [PATCH] Fix JSON wrong encoding tests on big endian platforms
+
+Fix test_json_without_specified_encoding_*_error tests on big endian
+platforms.  The tests wrongly assume that data encoded as "utf-32-be"
+can not be decoded as "utf-32".  This is true on little endian platforms
+but on big endian platforms "utf-32" is equivalent to "utf-32-be".
+To avoid the problem, explicitly decode as "utf-32-le", as this should
+trigger the expected exception independently of platform's endianness.
