encoding=None: this is the important one -- json is always UTF-8 yes?
Standard JSON is always UTF-8. Nevertheless, I'm quite sure that there's a ton of Japanese in Shift JIS, including some produced by default in Python on Windows. I'll bet the same is true of GBK for Chinese, and maybe even ISO-8859-1 in Europe.
So what should the json lib do with these? It could have an encoding parameter with utf-8 as default. Or it could require that the user open the file themselves if it's not UTF-8. BTW: I noticed that json.loads() takes: Deserialize ``s`` (a ``str``, ``bytes`` or ``bytearray`` instance containing a JSON document) to a Python object. A str is an str (already Unicode, yes?) -- but for bytes, it must be assuming some encoding, presumably UTF-8, but it doesn't seem to have a way to specify one -- so this is already a missing feature. -CHB -- Christopher Barker, PhD Python Language Consulting - Teaching - Scientific Software Development - Desktop GUI and Web Development - wxPython, numpy, scipy, Cython
