this plugin dont work with Hebrew (bug)

Hi,
i try to use your plugin but seems there are some bugs.

what i did is create new project:

main site: https://haifa-flowers.co.il
lang: Hebrew
country: israel
engine: http://www.google.co.il

keyword i use is: “פרחים בחיפה”

in the log file i see Search query is: (what i have notice that no matter what keyboard i will use or site the Search query gives the same result)

http://www.google.co.il/search?q=%25D7%25A4%25D7%25A8%25D7%2597%25D7%2599%25D7%259D%2B%25D7%2591%25D7%2597%25D7%2599%25D7%25A4%25D7%2594&num=100&start=0&client=firefox-a&pws=0&filter=0&safe=off&ie=UTF-8&oe=UTF-8&access=a&gl=IL&btnG=Search&hl=en&channel=fs

the right Search query in google is:
https://www.google.co.il/search?q=%D7%A4%D7%A8%D7%97%D7%99%D7%9D+%D7%91%D7%97%D7%99%D7%A4%D7%94&oq=%D7%A4%D7%A8%D7%97%D7%99%D7%9D+%D7%91%D7%97%D7%99%D7%A4%D7%94&aqs=chrome..69i57j0l5.4927j0j7&sourceid=chrome&es_sm=93&ie=UTF-8
