Error running query: 'ascii' codec can't encode characters in position

Issue Summary

I am getting an error on running queries.

Error running query: 'ascii' codec can't decode byte 0xc3 in position 7: ordinal not in range(128

Steps to Reproduce

1. Setup redash version 10.1.0 (2589bef)
2. Add postgresql datasource
3. In postgresql create database with SQL_ASCII encoding and create table with row containing 'ç'
4. In redash create query wich will select this row from postgresql or without tabe just query: "select 'ç' "

If we change database encoding to utf8 and run query again - we don't get error.

Technical details:

• Redash Version: 10.1.0 (2589bef)
• Browser/OS: chrome/centos7
• How did you install Redash: docker-compose

I tried apply this fix to our installation: #2165
But it doesn't help.

I add the following code in the /app/redash/task/queries.py file and it works fine

import sys
reload(sys)
sys.setdefaultencode("utf8")
