Package: python2.4
Version: 2.4.4-2
Severity: normal
Hello,
Thanks for maintaining Python.
While I can output unicode properly on a terminal, the same script does
not work when redirected to a file:
$ cat test.py
#! /usr/bin/python
# vim:set encoding=utf-8:
import sys
def output(s):
print s.decode('utf-8')
print sys.stdout.encoding
s = "ééé"
output("%s" % (s))
$ ./test.py
UTF-8
ééé
$ ./test.py > test
Traceback (most recent call last):
File "./test.py", line 12, in ?
output("%s" % (s))
File "./test.py", line 7, in output
print s.decode('utf-8')
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-2:
ordinal not in range(128)
$ cat test
None
A work-around for this is (courtesy of MadCoder):
import sys, codecs
if sys.stdout.encoding is None:
sys.stdout = codecs.open("/dev/stdout", "w", 'utf-8')
Ciao,
Enrico

This is not a bug in Python, but in the individual scripts. Scripts
should not rely on being able to write Unicode strings to stdout.
Instead, they need to encode strings explicitly, according to whatever
protocol is defined for whatever file they send the data to. In absence
of a more specific guidance from the user (or the protocol that they
follow), they should use locale.getpreferredencoding().
I propose to close this as "won't fix". Python 3 has resolved this issue
in a different way, explicitly distinguishing between text files (which
get encoded in the locale's encoding unless specified differently), and
binary files (which don't support writing Unicode to them).
