Facebook Login Chinese name problem

I used this plugin and found if user login via facebook and whose name is Chinese.

After facebook auth and redirect to site. It will connect with wp user database
then show an error.

I think it might be user name problem.

example: http://graph.facebook.com/sharon.huang.9615
This user’s name is Chinese.
“name”: “\u9ec3\u82e5\u6db5”,

so I modify hybridauth\Hybrid\Providers\facebook.php
change name to username, then work.
