Try this code:

from email.header import decode_header

def getheader(header_text, default="ascii"):
    """Decode the specified header"""

    headers = decode_header(header_text)
    header_sections = [unicode(text, charset or default)
                       for text, charset in headers]
    return u"".join(header_sections)

I get the following output for your strings:
