It depends on the output you want to have. One option would be


Then, s.write(u'\251') prints a string in Python quoting notation.


print >>s,u'\251'

won't work, since print *first* tries to convert the argument to a
string, and then prints the string onto the stream.

Since you are asking for a hack :-) How about having an additional
letter of 'u' in the "mode" attribute of a file object?

Then, print would be

def print(stream,string):
  if type(string) == UnicodeType:
    if 'u' in stream.mode:

The Stream readers and writers would then need to have a mode or 'ru'
or 'wu', respectively.

Any other protocol to signal unicode-awareness in a stream might do as


P.S. Is there some function to retrieve the UCN names from ucnhash.c?
