/*
* Joliet extensions for ISO9660. These are spottily documented by
* Microsoft. In their infinite stupidity, they completely ignored
* the possibility of using an SUSP record with the long filename
* in it, and instead wrote out a duplicate directory tree with the
* long filenames in it.
*
* I am not sure why they did this. One reason is that they get the path
* tables with the long filenames in them.
*
* There are two basic principles to Joliet, and the non-Unicode variant
* known as Romeo. Long filenames seem to be the main one, and the second
* is that the character set and a few other things is substantially relaxed.
*
* The SVD is identical to the PVD, except:
*
* Id is 2, not 1 (indicates SVD).
* escape_sequences contains UCS-2 indicator (levels 1, 2 or 3).
* The root directory record points to a different extent (with different
* size).
* There are different path tables for the two sets of directory trees.
*
* The following fields are recorded in Unicode:
* system_id
* volume_id
* volume_set_id
* publisher_id
* preparer_id
* application_id
* copyright_file_id
* abstract_file_id
* bibliographic_file_id
*
* Unicode strings are always encoded in big-endian format.
*
* In a directory record, everything is the same as with iso9660, except
* that the name is recorded in unicode. The name length is specified in
* total bytes, not in number of unicode characters.
*
* The character set used for the names is different with UCS - the
* restrictions are that the following are not allowed:
*
* Characters (00)(00) through (00)(1f) (control chars)
* (00)(2a) '*'
* (00)(2f) '/'
* (00)(3a) ':'
* (00)(3b) ';'
* (00)(3f) '?'
* (00)(5c) '\'
