Go back to when it worked?
As to why it's a guess why since no one can see what the machine is or what happened.

Somehow , the Unicode format on my xp (sp3) computer was replaced with ANSI format . so all documents in Arabic were replaced with unreadable Latin letters , even programs that use Arabic language in its opening screen were replaced with the same kind of unreadable letters .
How can I restore the old Unicode format ?
