I managed to view reports in arabic by changing web.xml but my problem is to have buttons or titles in html written in arabic. after saving the file to unix from developer studio it appears as question marks. any one can help??

This is most likely not a WebFOCUS problem.

I Googled "unix arabic html" and from the many results, I found this site that may be helpful:
