UnicodeEncodeError

[isublimity]

Find some bug, if i create "Time Series - Line Chart" and use "Group by" - field containing Russian utf-8 chars i get error "UnicodeEncodeError", but if create simple "pivot table" all OK.

Traceback (most recent call last):

Oh no! Unicode errors... Until we iron that out, can you try on python3 by any chance?

I found the solution to my problem, file
https://github.com/airbnb/caravel/blob/master/caravel/viz.py#L702
name = ["{}".format(s) for s in name]
Replace with
name = ["{}".format(s.encode('utf-8')) for s in name]

The first time I have been programming in Python, can greatly mistaken;)

I think this is fixed now with the from __future__ import unicode_literals I sprinkled on all files
