What version of Python do you use ?
With IDLE:
Python 3.4.0 (default, Apr 11 2014, 13:05:11)
[GCC 4.8.2] on linux
Type "copyright", "credits" or "license()" for more information.
>>> print("€"*10)
€€€€€€€€€€
>>>
With IDLE and Python 2.7, there seem to be an encoding problem:
>>> s = u"€"*10
>>> >>> import sys
>>> sys.stdout.encoding
'utf-8'
>>> print s.encode("utf-8")
â¬â¬â¬â¬â¬â¬â¬â¬â¬â¬
>>> print s.encode("latin1")
€€€€€€€€€€
But with python2 on console, it works nicely:
laurent@litchi:~$ python
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more
information.
>>> s = u'€'
>>> s*10
u'\u20ac\u20ac\u20ac\u20ac\u20ac\u20ac\u20ac\u20ac\u20ac\u20ac'
>>> print s*10
