Geting some rubbish in the name of the disk

[Paul Smith]

Dear All

To create an ISO file of a movie I use the command:

mkisofs -o dvd.iso -V "Movie Name" -dvd-video -v /path/to/DVD

However, if the "Movie name" is a string containing accented letters,
then I get some rubbish in the name of the disk when its icon appear
on KDE desktop. How can I circumvent this problem? Since I do not have
any external DVD player (I have got only the one on my computer), will
the same rubbish appear on TV when the disk is played?

Thanks in advance,

Paul
