This has now been solved by doing this:

First, start tomcat by changing catalina.sh,
the "start" section, by prepending the line
saying:
"$_RUNJAVA" $JAVA_OPTS $CATALINA_OPTS ...
so that it reads:
LC_CTYPE=en_US.ISO-8859-1 "$_RUNJAVA" $JAVA_OPTS $CATALINA_OPTS ...

Than fixes the problem. It seems that Tomcat
cares only for LC_CTYPE and not LANG.

Strangely, it did not work to export LC_CTYPE within
catalina.sh, you had to set it on the line as above.

Restart tomcat, and it should work. At least it did for us.

It had nothing to do with charsets.jar, the class for
ISO-8859-1 resides in rt.jar.

Still don't know why all this changed from
previous versions.

Kind regards
Rikard
