Simon, good point.  I was thinking of portability in terms of
completely different operating systems, say AS/400 and Windows (e.g.
ILE RPG and VA RPG).

For CCSID to CCSID portability, you shouldn't code literals in your source
unless they are invariant characters (apostrophe is invariant).  Instead,
you should put your "literals" in a file and read them in at runtime.
