No. Files contain bytes, not characters; you have to encode the Unicode
object when writing to a file (or StringIO object).
As Diez suggested, use the codecs classes:
py> import codecs
py> from StringIO import StringIO
py> orig_file = StringIO()
py> wrapped_file = codecs.getwriter('hex')(orig_file)
py> wrapped_file.write("Hello world!")
py> wrapped_file.getvalue()
