Jon Hanna has launched himself into webspace with a true tour de force: Entry-Level Unicode for XML. This article covers just about all you need to know about using Unicode with XML, either as an application or parser developer. My only nit is that I wish Jon had put the long appendices on separate pages - many people will want to print out the article and they won't necessarily need the code samples. Apart from that, this is definately a document to point newbie XMLers to in the future.
