I'm working with iOS apps and sometimes their names have special characters and when this apps make requests to my server, the import_log.py script fails to parse this lines. This only happens when using nginx_json format.

Here's an example:

{"ip": "1.1.1.1","host": "blabla.com","path": "/api/test.xml","status": "200","referrer": "-","user_agent": "F\xFAtbol/1.0 (iPhone; iOS 7.1; Scale/2.00)","length": 267,"generation_time_milli": 0.009,"date": "2014-04-16T14:56:24-03:00"}

Check that user_agent has a special character and that the script fails when parsing this lines.

Thanks
