AppEngine - error uploading data to local server

I am following AppEngine tutorial on this website When I try to upload data to local server using this script(upload_data.bat):

#!/bin/sh
C:/Program\ Files\ \(x86\)/Google/google_appengine/appcfg.py upload_data --config_file bulkloader.yaml --url=http://localhost:8888/remote_api --filename $1 --kind=$2 -e [email protected]

I get error:

$ upload_data.bat places.csv Place

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc4 in position 13: ordinal

What could be the problem?
