json.dump fails to dump Unicode strings #988

Open ironpythonbot opened 9 years ago

ironpythonbot commented 9 years ago

Demonstration of the problem is below. With CPython this works fine and the result is, as expected "\u00e4".

IronPython 2.7 (2.7.0.40) on .NET 4.0.30319.261

import json
from StringIO import StringIO
s = StringIO()
json.dump(u'\xe4', s)

I just hit this yesterday. Not being able to easily use unicode strings for json seems like a big usability issue. To get around the bug without modifying the standard library, I encoded all my strings to utf-8 before encoding into json. It's ugly, but it works. But it's ugly...
