Hi, Marion,
yes, QuarkXPress 8 will open ANY version of documents back to QuarkXPress 3.1.
So also documents of versions 4, 5, 6, and 7, regardless whether they are multi-lingual, single-lingual or even East Asian.
Fonts are definitely something to be aware of, as you might have used fonts from the 1990's, which COULD cause issues under modern Operating Systems (and then also with QuarkXPress). That said, your fonts might also work fine.
Printer drivers is another area, as you are probably not only upgrading your QuarkXPress, but also the OS.
And if you are using a required XTension in your current version of QuarkXPress, then check first whether it is also available for 8.
Maybe best to try QuarkXPress 8 yourself, the Test Drive of 8 is fully functional for 60 days and you can try EVERYTHING.
You even get FULL support during the 60-days test: http://support.quark.com (call us, chat with us, email us).
Best
