CrystalReports

I have a crystal report in a web site developed by ASP .NET 4, the report is working well on any local PC.

But, when I uploaded the site some bound fields appears as "?????" on the browser, these fields that appears with this format is in Arabic.

Notice >>
** Database Collation is "Arabic_CI_AS" and supports Arabic language, and there are some other pages in my site has a GridView and data displayed on it without any problems.
** Pages Encoding is UTF-8.
** Report Font is "Arial", and it is supported in all browsers.
** Another amazing this is shown in the next image, TextObject in the report appears correctly although it was written in Arabic and Arial font. You can see it from here
