It totally breaks Mozilla, BTW. Konqueror and MSIE both render your page correctly. Maybe I should send in a bug report ...
Thanks for this note, would you be interested in working with Roberto to get it cleaned up a bit and added to our documentation?
Also, have you talked to Henry Minsky about i18n and ACS Classic 4.x? I know that there's been a lot of aD discussion on the matter but I've not followed it closely. Since you've been in contact with Henry, I'm hoping that maybe you know whether or not 4.1 will be better in this regard out-of-the-box, i.e. allowing for the parameterization of the charset when a package is installed or something like that.
