+ utf8 option.

+

+ extensions set the permissions otherwise
+ dmode=xxx Sets the permissions on directories to xxx unless Rock Ridge

+Quoting from the PDF "This 2nd Edition of Standard ECMA-119 is technically
+identical with ISO 9660.", so it is a valid and gratis substitute of the
+official ISO specification.
