I have had success using Mark McClure's tools:

on archive.org

Your polyline works for me when I use this tool to decode it:

on archive.org

and this to display the results:

Encoded polylines often have issues with "\" escaping the next character.

See this example [1] (can't seem to get it to display as a link)

with each '\' changed to a single '\' From this issue where it does display as a link.

The Google APi have a parameter now: path=enc:

"https://maps.googleapis.com/maps/api/staticmap?
size=300x300&key=YOUR_KEY&path=enc:" + direction.routes[0].overview_polyline
