How to print Unicode character in Python?
...er('utf8')
sys.stdout = UTF8Writer(sys.stdout)
print(u'e with obfuscation: é')
Run it and pipe output to file:
python foo.py > tmp.txt
Open tmp.txt and look inside, you see this:
el@apollo:~$ cat tmp.txt
e with obfuscation: é
Thus you have saved unicode e with a obfuscation mark on it ...
