You should know that since about 6 months I am the maintainer of mkisofs.
Mkisofs is a plain POSIX program that uses readdir() to read directory
content. It has been compiled using Cygwin-b20 and behaves the same way
as ls. 

To debug you could create a CD on UNIX that uses Joliet and includes
a file Jörg. Mount this CD on Win32 and do a ls -l | cat -v and you will
see that there is ~^T resp. M-^T instead of the expected ö (which
should be M-v)

Did this behaviour change since B20 ?

If you like to have a look at mkisofs, get
