This Joliet extension is designed to solve these problems. That is, you can download it and check it out, but if you want to use it, you are expected to pay for it. 1.4.2 is the current version as of June 3, 2001. See here for known problems.
Previous versions are available via ftp .
Version 2.0 is not finished yet. Check back in Mid-June. Apple is supposedly working on their own implementation for that. I have not tried it out myself yet, but others told me that it works somehow, although not perfectly, already. I have a Windows network connection, Windows-formatted hard disks, ZIP, JAZ etc.
