mkisofs is a pre-mastering program that generates binary ISO9660
filesystem image. Users can then write the image to devices like
CD-R or CD-RW. This port can also generate Chinese Big5 filenames
on Joliet filesystems. Use the -J option to activate it.
Although it works flawlessly, further improvements are possible:
1. Accept GB(Simplified Chinese) filenames also.
2. Upgrade to mkisofs 1.13. 1.13 uses a better structure to manage
I18N, which is (almost all) borrowed from Linux kernel's fs code.
