You probably need to pass the iocharset mount option.

If nobody has a better idea, you could create a loop device with a HFS filesystem, copy the CD to that filesystem, replace all bad filenames, then copy everything to a normal filesystem.

Edit: apparently there’s a --iconv option in rsync: https://askubuntu.com/a/540960

Not sure what the actual question is here, but if the files are there, the filesystem is mounted properly using hfsplus, and you can read the files, then any incompatible characters will be properly substituted, and the files can be copied.

Your friend will just have to put some work into properly renaming then afterward.
