That is exactly what I did: # -*- coding: utf-8 -*- and then EDGE_LABEL=[u'∈'] and the script file stored in UTF-8 without BOM. And here is the error I got: Traceback (most recent call last): File "apply-rules.py", line 473, in <module> execfile("rules.py") File "rules.py", line 13, in <module> signature=['204:6', '20456:4', '2045654:4', '45654:2', '456:2', '654:2', '2:3', '4:3', '6:1'] File "apply-rules.py", line 292, in apply_edge_rule r=att_edge(q,KNOWN[ms[0][0]],KNOWN[ms[0][5]],globals()[ms[0][3]]) File "apply-rules.py", line 351, in att_edge g.ep['labele'][res]=str(g.vp['labelv'][a])+"_"+EDGE_LABEL[val]+"_"+str(g.vp['labelv'][b]) File "/usr/local/lib/python2.7/site-packages/graph_tool/__init__.py", line 490, in __setitem__ self.__map[key] = self.__convert(v) File "/usr/local/lib/python2.7/site-packages/graph_tool/__init__.py", line 254, in convert return vtype(val) UnicodeEncodeError: 'ascii' codec can't encode character u'\u2208' in position 3: ordinal not in range(128)

So the problem is not yet how to make the symbol appear in graphviz output, but how to make the Python code run…
Well, you should really read Python's documentation:
https://docs.python.org/2/howto/unicode.html
in short you should start your script with:
#!/usr/bin/env python # -*- coding: utf-8 -*-
example = u'abcdé'
(I'm assuming you are using python 2. With python 3 it is simpler, since it accepts utf-8 by default.)
Best, Tiago
Ps. Note that graph_draw() *does not* use graphviz!
