Unicode support

[miracle2k]

I scalars.py, this line:

def coerce_string(value):
    if isinstance(value, bool):
        return 'true' if value else 'false'
    return unicode(value)

If the input value of a mutation is a unicode string, I get a decode error. A simple fix, unicode(value) handles this for me.

Hey. Can you provide code to repro the case where this happens, so we can put it in as a unittest?

Thanks!

I think the "If the input value of a mutation is a unicode string" is the test case ;)

It shouldn't though. Which is why I'm wondering what's causing the error.
