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?

Try the following script:

#!/usr/bin/env python

import syck
from datetime import datetime

for i in range(10000):
    now = datetime.now()
    dumped = syck.dump(now)
    loaded = syck.load(dumped)
    if now != loaded:
        print "original:", now
        print "result:", loaded
        print "dump:", dumped
        break

I get:

original: 2007-09-17 11:04:08.091612
result: 2007-09-17 11:04:08.916120
dump: --- !timestamp 2007-09-17T11:04:08.091612

The YAML looks OK, so the parsing is wrong.

Reported by sproaticus, 6 years ago.

A scalar value token consisting of just a period ('.') is interpreted as a float value. When construct_yaml_float() creates a float using this value, it throws an uncaught ValueError instead of yaml.YAMLError

(Also, what's PIL doing in the stack? I didn't import it.)

>>> yaml.load('yaml: .')
