I have some books made on CS4 on Windows 7. I have a new machine which has Windows 8 and now I have installed CS4 on the new machine, some of the characters are not showing properly. If I open the same file on my Windows 7 machine, i can see it without any problems.
I then installed the "Arabic Enabled" CS6 trial and still had the same problem. I used the workaround script to use Arabic on CS4 standard version and not the ME version.
The whole books is almost in Arabic so I can't really afford to retype the whole thing.
