Hello - me again.
Obviously I shouldn't have said that iWeb is dead - it's just an application that can still be used, though not with MobileMe in the future.
I guess what I'm really asking for is the next best combination of Unicode support, strong integration with some of the Mac's other programs for audio/photos/video and ease of publishing when it's all done.
Sandvox has a very iWeb like GUI and has an option to change languages. I've not used it but it would be a reasonable replacement for iWeb.
iWeb will still be viable for a long time to come and multi-languague sites can be created with the help of Language Switcher.
The wife wants to make a home web site (photos, blog/commentary - the usual) that has two languages on the same pages (mixing English and Korean)
I think every modern web editing app will create pages in UTF-8 encoding, which is what is required to have multiple languages on the same page. As long as what is on the page is created by the author, you should have no problem. But things created by the app, like buttons to "make a comment" could be a different issue.
