I want to read and write unicode on stdin and stdout. I can't seem to
find any way to force sys.stdin.encoding and sys.stdout.encoding to be
utf-8, so I've got the following workaround:
import codecs, sys
out = codecs.getwriter("utf-8")(sys.stdout)
def tricky(): return sys.stdin.readline().decode("utf-8").[:-1]
That is, I wrap sys.stdout in a utf-8 writer and I read utf-8 input
from stdin as normal characters then convert it to
unicode and chop off the newline. Wrapping stdin with
codecs.getreader() doesn't work for some reason--when I call readline()
on the resulting wrapped stream, it won't return until I send it Ctrl+d
twice! Then stdin is closed which is of course not helpful.
