Setting default output encoding

[Torsten Bronger]

Hallöchen!

I start a python script with subprocess from another Python script
with

python = subprocess.Popen(["python", "myscript.py"],
stdout=subprocess.PIPE, stderr=subprocess.PIPE)

However, this child script has sys.stdout.encoding set to None,
which means that Unicode strings cannot be printed without trouble.
I tried

environment = os.environ
environment["LC_CTYPE"] = environment["LANG"] = "de_DE.UTF-8"
python = subprocess.Popen(["python", "myscript.py"],
env = environment,
stdout=subprocess.PIPE, stderr=subprocess.PIPE)

for setting it to UTF-8, however, it didn't work. Any idea on how
to achieve this?

Tschö,
Torsten.

The automatic setting of .encoding is only done when the output is a
terminal. If you write to a file, or a pipe, Python's guess as to what
the encoding of that stream is might be easily wrong.

If you want to be able to write Unicode strings to stdout always,
it's best to wrap stdout with the result of codecs.getwriter. If
you want to use the user's locale as the encoding, use
locale.getpreferredencoding().
