Using codecs.open, when you read the file you get Unicode. When you
print the Unicode object, it is encoded using your terminal default
encoding (utf8 I presume?)
But when you redirect the output, it's no more connected to your
terminal so no encoding can be assumed, and the default encoding is
used.
Try this line at the top:
print
"stdout:",sys.stdout.encoding,"default:",sys.getdefaultencoding()
I get stdout: ANSI_X3.4-1968 default: ascii normally and stdout: None
default: ascii when redirected.
You have to encode the Unicode object explicitely: print
fileString.encode("utf-8")
(or any other suitable one; I said utf-8 just because you read the
input file using that)
