This still applies. While I doubt anyone would name their constants "privet", it might be useful to have this option. I'll just mark this as Accepted (rather than New), but I don't think I'll be able to fix it.

**Status:** Accepted

This seems to be a python2 issue. This bug is totally still present if you're running python2, and I'm looking to see if I can figure out how to fix it for python2, but in python3:

>>> from sympy import *
>>> a = symbols("ПРИВЕТ")
>>> pretty_print(a)
ПРИВЕТ
>>> pretty_print(sin(a))
sin(ПРИВЕТ)
>>> pretty_print(a/2)
ПРИВЕТ

Is it just a matter of putting u before the " ?

It breaks in new and different ways (in python2) if you add the "u", including not correctly printing if you just type "a" into the prompt.

I noticed that IPython seems to have some issues of its own.

Nevermind, that was an issue with my IPython profile (it turns out that if you use \M-P in your readline parse_and_bind, it conflicts with П; the solution is to use \eP instead).

This can be closed now that python 2 is dropped.
