Unicode, WWW, Databases and Japanese Web Sites?

Matthew Branton asks: "I have recently started working on a database driven Japanese language web site, and frankly I am getting lost in a sea of complicated Unicode madness. I was toying with the idea of using Python 2.1, PostgreSQL and the mxODBC interface, has anyone else had experience with this particular setup? Are there more appropriate free solutions available, perhaps JSP/Servlet based?" Unicode received a a lot of coverage this week, on Slashdot, and maybe that's due to the increasing worldwide popularity of the net and the desire to read and work in the character sets for users of a given nationality rather than trying to have it all fit in Latin-1. Do Python, PostgreSQL or mxODBC have any issues with Unicode?
