Failed to set UTF-8 encoding for output redirected to file.
# -*- coding: UTF-8 -*-

import sys

print sys.stdout.encoding
print sys.getdefaultencoding()


=== Output to console works fine ===

$ java -jar jython.jar -Dpython.console.encoding=UTF-8

=== Output to file does not work ===

$ java -jar jython.jar -Dpython.console.encoding=UTF-8 > tmp.txt 2>tmp2.txt ; cat tmp.txt
$ cat tmp.txt
$ cat tmp2.txt
Traceback (most recent call last):
  File "", line 9, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\u0424' in position 0: ordinal not in range(128)

in there is this code fragment in initEncoding:

            if (stdStream.isatty()) {
                stdStream.encoding = encoding;

So the encoding is only applied if the stream is a tty. 
When the check was removed, your code example works fine.
I'm not sure why this check is there?

I think it because of property name '-Dpython.console.encoding=UTF-8'.
It is CONSOLE encoding, not output encoding...

Can we add properties python.stdout.encoding and python.stderr.encoding?
Can we then change the code of initialization of the streams?

python.console.encoding - applied when stdout of stderr is a terminal.
python.stdout.encoding - applied when stdout is not a terminal, or when it is terminal but python.console.encoding is not set.
python.stderr.encoding - same as python.stdout.encoding.
