[jdom-interest] Turning of entity expansion

Wed Sep 4 00:15:24 PDT 2002

OK, so JDom has helpfully converted a character (the &) that could
be confused with an XML reserved character(<, >...) into &amp; for you.
This is normally what you would want, so I doubt it can be turned off.

JDOM does not know that &#169; is already encoded for XML, so it tries
to do it for you.

This comes back to your original comment:

So, why is the actual character not acceptible? I am not saying you
are right or wrong to want the original character, I am trying to
ascertain the reason why the translated character is not acceptible
to you. The copyright symbol appears quite happily in my browser
when I use it. Like this: ©
