I have a sample page with some JIS X 0212 kanji and accented characters
at: http://www.csse.monash.edu.au/~jwb/wip.html

Not so. Practically no-one on the planet uses JIS X 0212 characters
in EUC-encapsulated text in WWW pages. The reason is 
<drumroll>IE doesn't support the full EUC-JP</drumroll>.

Yup. I have an u-umlaut, etc. on that sample page.

Spot on.

They either use UTF8 or encode the diacritics using HTML things like
&ocirc;

In my WWWJDIC server, all the data files are in EUC. If you set your
dialogue (by cookie) to run in EUC or Shit_JIS (EUC is the default), the 
output routines substitute HTML entities for the diacritics, etc. and 16x16 
images for kanji and kana (yes, JIS X 0212 has a few extra kana.) If you set 
it to UTF8, the raw codes go out. (This only applies really to the few
dictionary entries with JIS212 kanji, the German file and the Buddhism
file.)

That's how I do it anyway. I started off putting out full
EUC-encapsulated JIS212, but realised most of my users couldn't see it.

Cheers

Jim
