Your terminal or console is failing to let Python know it supports UTF-8.
Without the from __future__ import unicode_literals
line, you are building a byte string that holds UTF-8 encoded bytes. With the string you are building a unicode
string.
print
has to treat these two values differently; a byte string is written to sys.stdout
unchanged. A unicode
string is encoded to bytes first, and Python consults sys.stdout.encoding
for that. If your system doesn't correctly tell Python what codec it supports, the default is to use ASCII.
Your system failed to tell Python what codec to use; sys.stdout.encoding
is set to ASCII, and encoding the unicode
value to print failed.
You can verify this by manually encoding to UTF-8 when printing:
# encoding: utf-8
from __future__ import unicode_literals
name = 'helló w?rld from example'
print name.encode('utf8')
and you can reproduce the issue by creating unicode literals without the from __future__
import statement too:
# encoding: utf-8
name = u'helló w?rld from example'
print name
where u'..'
is a unicode literal too.
Without details on what your environment is, it is hard to say what the solution is; this depends very much on the OS and console or terminal used.
