Is there any CD/DVD burning app/ISO format which supports files and directories with long non-English (unicode) names? Apparently Joliet-long ISO standard supports filename up to 103 characters, but I'm not sure if it supports unicode as well, and if Brasero or any other Gnome app can burn DVDs with this format. I found out that an app called gBurner does quite a decent job, but unluckily it's a Win app.

I have to burn the contents of my external HDD, but since my data contains many downloaded pages (with companion HTML pages' directories containing pictures, JS scripts, CSS styles, and so on) and since many of those filenames contain non-English characters, I need some app/format to be capable of burining them safely on a DVD (without the old-fashioned need to compress the contents under a English filename), such that the content is readable on Linux and Win machines.
