Software Deployment

Ok here is a weird one for you.   I have this software that I finally figured out how to silently install as it is a two part installer where one part needs some old DirectX 9 runtimes installed first.   The second part is the actual program.   The problem comes in when I try to ZIP up the Installer folders with my install.bat and the setup.iss file I created it fails because there is a manual in PDF form that has a ® symbol in the filename.   So I thought remove that symbol right??  NOPE!   If I do that the installer hangs and fails because it is looking for that specific PDF with the exact filename symbol and all.   So does anyone know how I can ZIP up a file that has that symbol so that when it is unzipped it will still have that symbol in the filename.    I have to deploy this software to 60 computers and I rather not have to install it by hand.

NOTE: 7zip will zip up the file and unzip it with the ® symbol in the file name in my tests with a text file but if you use the built in ZIP features of Windows it does not unzip the filename properly.   I have not tested this with KACE but I do not know what it uses to extract it's zip files
