[jdom-interest] Kana symbols and UTF-8? (was Re: Kana characters?)

This is really why (IMHO) it's very dangerous to represent XML documents as 'Strings', the 'encoding=' portion of the prolog tells the parser how the characters are encoded in the following stream of bytes.
I believe it's legal (but somebody might shoot me down on this) for the prolog to have an encoding of 'us-ascii' (ie single byte characters) and then to use the XML character escapes (&#xnnnn) to represent the extended character set.
So, when using any xml serializer (and JDOM would fall into this category) you need to ensure that the character encoding of your java.io.Writer matches the encoding specified in the prolog.

OK, now I'm a little confused.   I guess this is an XML question and not really a JDOM question, but perhaps someone can explain it.

Where I get lost is in the <hiriganaSym> tag.   Those characters inside are not part of any 8-bit code (ASCII, UTF-8 or whatever).  Java has no problem with it because all String objects are built on unicode, but what does the encoding="UTF-8" mean in the header if these symbols can show up in the document?
