Hi all,

I'm puzzled by a strange behavior of yaml

If you run the attached script you obtain an output like this:

{'date': '732638',
'fields': {},
'guid': '0000010f153544cf8a314808007f000000000001',
'expiration': None}
{'date': '732638',
'fields': {'': {}, 'it': {'title': 'Hello World'}},
'guid': '0000010f153544cf8a314808007f000000000001',
'expiration': None}

*Please note the 'fields' value (I wrap the output to increase legibility)*

the first line is printed inside this custom constructor function:

def news_constructor(loader, node):
    nodes = loader.construct_mapping(node)
    print nodes
    return nodes

the second line (the correct one) is the print of the return values of this function

Can you help me or explain me this strange behavior?

Hello, I'm looking for support, but I don't know if this is the right place to ask.

I'm using PyYAML to load some nested data from an utf-8 encoded file in Python with:

import yaml
stream=file('data.yaml','r')
data=yaml.load(stream)

The data variable becomes a dictionary with unicode values where is needed. What I want is to put utf-8 strings instead of unicode values to use this data with another library: Cheetah. If I try to use the unicode-type dictionary generated by default with PyYAML I get an UnicodeDecodeError, because de Cheetah strings are in iso-8859-15 and Python tries to decode them to Unicode using ASCII charset tables, so it obiously fails.

Is there any way to get an utf-8 coded dictionary?
