Seed compilation fails with non-ascii character in v0.14.0

[brian-bk]

Issue

Dbt seed fails if seed file contains a special character. This is new in v0.14.0, in v0.13.1 it was working for us. This looks like #1616 could be related.

Issue description

When running dbt seed, dbt fails with output:

Encountered an error:
Compilation Error in seed nonascii (data/nonascii.csv)
  'ascii' codec can't encode character u'\u2013' in position 6: ordinal not in range(128)

System information

The output of dbt --version:

installed version: 0.14.0
   latest version: 0.14.0

OS: MacOS
Python version: 2.7

Steps to reproduce

Here's a sample csv:
nonascii.csv.zip

It has contents:

id
Uh – Oh

(note the – is not a plain -)

Thanks for the report @brian-bk -- I think that #1452 might be relevant here. We'll check it out!
