When printing to the console, Python looks at sys.stdout.encoding
to determine the encoding to use to encode unicode objects before printing.
When redirecting output to a file, sys.stdout.encoding
is None, so Python2 defaults to the ascii
encoding. (In contrast, Python3 defaults to utf-8
.) This often leads to an exception when printing unicode.
You can avoid the error by explicitly encoding the unicode yourself before printing:
print (unicode_obj.encode('utf-8'))
or you could redefine sys.stdout
so all output is encoded in utf-8
:
import sys
import codecs
sys.stdout=codecs.getwriter('utf-8')(sys.stdout)
print(unicode_obj)
