[sexybookmarks shareaholic] Big problem with my url (title encode)

I have a big problem with the title (?title=something) that is encoded in special caracter (Arabic), which is too long on Internet Explorer, like this:

https://www.mysite.com/833/%d8%ad%d9%8a%d9%86-%d9%8a%d8%ad%d8%b6%d8%b1-%d8%a7%d9%84%d9%84%d9%91%d8%a6%d8%a7%d9%85-%d8%b9%d9%84%d9%89-%d9%85%d9%88%d8%a7%d8%a6%d8%af-%d8%a7%d9%84%d8%a3%d9%88%d8%b7%d8%a7%d9%86/

When I try to share the url seems to be truncated,there are some field not transmitted, i have the following error

An Error Was Encountered

The service field is required.

The v field is required.

The apikey field is required.

how can I solve this problem?

thanks!
