Panel group and national character sets.

My system is operating under CCSID 278 (Swedish). All user profiles are
also running under this CCSID and so are the interactive jobs.

I have a source file QPNLSRC for panel group source. The CCSID for this
source file also happens to be 278 - coincidentally.

I use panelgroups exclusively for help texts for commands and displays
but there is a problem with national characters that I do not seem able
to get around.

An example: I generated help source for a command. I then entered
additional text for the various help sections and as the text is in
Swedish it contains a bunch of the national characters like "a with a
ring", "a with trema" and "o with trema".

That all looks fine as I edit the source (in RDI or SEU).

BUT when I run the command and call up the help text those characters
all  come out as "{", "}" and "|"  instead.

It should be possible to use any character set for panel groups should
it not?
