Joliet is a Microsoft extension and profile of ISO 9660 (CD-ROM) format to support Unicode filenames. It is often compared to Rock Ridge and related extensions, though it works in an entirely different way.
[edit] Identification
Robust detection of Joliet requires iterating through all the volume descriptors, but in most cases, one of the following byte sequences will appear at offset 34904 or 36952:
-
25 2f 40(escape sequence for UCS-2 Level 1) -
25 2f 43(UCS-2 Level 2) -
25 2f 45(UCS-2 Level 3)
