In python3, I have had problems printing unicode characters to stdout, with the script failing, until I set this at the top of the file:

sys.stdout = codecs.getwriter('utf8')(sys.stdout.buffer)

but this then buffers the output, and I'd like to see the output as it is generated, line-by-line. What should I alter to stop the buffering?

Back up a step - how are you printing to stdout? Using normal `print` I hope? – Two-Bit Alchemist Sep 06 '16 at 15:51
yes, just normal print(). I think the problem is that I can't set the locale in the terminal I'm using, but the line above seems to fix that. – user2667066 Sep 06 '16 at 15:57

What OS are you using? – Remy J Sep 06 '16 at 16:45
There is some Python2 vs. Python3 difference, see here: http://stackoverflow.com/questions/4374455/how-to-set-sys-stdout-encoding-in-python-3 – VPfB Sep 06 '16 at 18:09
@RemyJ it works on OS X, but not on FreeBSD, FWIW – user2667066 Sep 06 '16 at 22:27
According to [mike](http://stackoverflow.com/a/21968640/6683985) it seems that the characters that Python can print are bound to the environment from which it was initiated... – Remy J Sep 06 '16 at 23:18
