Hi,

We're running Python SDK (ovirt-engine-sdk-python) ver 4.1.4 and we're having some issues getting values that contain accents. For example, this snippet fails:

    import ovirtsdk4 as sdk
    import ovirtsdk4.types as types

    # Create the connection to the server:
    connection = sdk.Connection(
        url='https://fqdn/ovirt-engine/api',
        username='...',
        password='...',
        ca_file='...',
        debug=True,
    )

    users_service = connection.system_service().users_service()
    users = users_service.list()

    connection.close()

This snippet fails in the "users = users_service.list()" line, because one of the records have a tilde (ó).

The trace is:
Traceback (most recent call last):
  File "lista_users", line 23, in <module>
    users = users_service.list()
File "/home/ovirt/prueba/ejemplo2/lib/python2.7/site-packages/ovirtsdk4/services.py", line 22155, in list
    return self._internal_get(headers, query, wait)

    return future.wait() if wait else future

    return self._code(response)

    return self._internal_read_body(response)
File "/home/ovirt/prueba/ejemplo2/lib/python2.7/site-packages/ovirtsdk4/service.py", line 310, in _internal_read_body
    return reader.Reader.read(response.body)
File "/home/ovirt/prueba/ejemplo2/lib/python2.7/site-packages/ovirtsdk4/reader.py", line 297, in read
    cursor = xml.XmlReader(io.BytesIO(source.encode('utf-8')))
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1899: ordinal not in range(128)

Opening the source code (ovirtsdk4/reader.py) file and seeking the exact line that fails I can see:

        if isinstance(source, str):
            cursor = xml.XmlReader(io.BytesIO(source.encode('utf-8')))

If I add a line just after the 'if' being "cursor = cursor.decode('utf-8')", it seems to work, but I guess the source code should handle this kind of situations.

Is this a known issue? Should I open a BZ? Any workaround meanwhile?

Thanks.
