Running scripts with RESTful APIs

[playtech_wpt]

what are the correct separation? I haven't found nothing on it..
I've tried all spaces; spaces+tabs; spaces+tabs+newline; tabs+newline. All encoded and all failed (((

here is the simple script to test:
logData 0
navigate https://google.com
logData 1
navigate https://facebook.com

and one of the tried POST:
POST http://www.webpagetest.org/runtest.php

POST data:
label=testApi&location=ec2-eu-west-1%3AChrome%3ANative&runs=3&fvonly=0&script=logData+0+navigate+https%3A%2F%2Fgoogle.com+logData+1+navigate+https%​3A%2F%2Ffacebook.com&video=1&k=...&tcpdump=1&mobile=1&tester=IP-AC1F1799&timeline=1&ignoreSSL=1

And all I get is always - "Invalid Script (make sure there is at least one navigate command and that the commands are tab-delimited). Please contact us if you need help with your test script.
