Yes, you are absolutely correct.  If you know which 
application server you are running on and you know the details
of the underlying servlet code, then you can use this
technique.  We are trying to write JSP code that will run
on a variety of app servers with both European and Asian
characters.  

Supposedly this should be possible because Java's internationalization
support is excellent and so is their cross platform support.

I wish it were actually so.

As I said in the previous email, there is no hole in 8859_1 (at least
Sun's java). Try running a program I attached to the previous email by
changing the encoding to "8859_1".

We have been using this technique, or hack, for a long time and it
works fine. The catch is that it works only when the default encoding
is 8859_1. If the servlet JVM's default encoding is Cp1252 and/or the
servlet is configured to use Cp1252 when converting the parameters, it
fails miserably.
