Passing encoding to Blaze URI's

[firecat53]

Hey, I'm just starting to look at incorporating your work on Blaze into tabview (firecat53/tabview#127) and was wondering if there's a way to pass the encoding on to Blaze?

Trying gtabview file:///path/to/tabview/samples/test_latin1.csv gives:

Traceback (most recent call last):

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xae in position 460: invalid start byte

Trying to pass the encoding with -e doesn't seem to help. Ideas?

Thanks, Scott

Maybe @cpcloud or @llllllllll can help on this

What version of Python are you using ?

It looks like we are not forwarding the encoding to the csv header check. I will update this.

I have a fix that allows us to open this file when encoding=latin1 is passed to resource, Data or CSV
