[igraph] Problem with displaying vertex's label text in Chinese characters

[何翔]

I use python-igraph-0.7 on Ubuntu to draw graph.  To display the vertex's text, I add its label attribute . As the text are Chinese characters of 'unicode' type (not 'str' type),  I encode them by "UTF-8". But when the graph is shown, the Chinese characters are show as the small squares, unreadable codes. The fragment of my code list as follows:

>>> g_labels = [n.encode('utf8') for n in g.vs['name']]

>>> plot(g, mark_groups=True, vertex_label=g_labels)

What's wrong with this?

thanks a lot.
