Background information

Mac OS X causes illegal file names to be reported when it reads some of the font data used in the Vietnamese End User License Agreements, which are installed in the Legal or Legal.localized folders. This problem causes severe file system and hard disk corruption if the files are not deleted or if the file system is not repaired.

This problem has been reported to Apple.
