CORBA24 — URLs interact poorly with code set selection

The corbaname & corbaloc url formats provide a situation where an IOR
designating a server is created and used by a client without input by
that server.

One (optional) element of an IOR is a CodeSetComponent specifying the
code sets that the server is willing/able to utilize. Normally these are
examined by a client and used to select a pair of code sets (narrow and
wide) to be used for communication between client and server.

Chapter 13 of the Corba spec states: "If the code set component is not
present in a multi-component profile structure, then the deault char
code set is ISO 8859-1 for backward compatibility. However, there is no
default wchar code set. If a server supports interfaces that use wide
character data but does not specify the wchar code sets that it
supports, client-side ORBs will raise exception INV_OBJREF."

This seems to imply one of the following:
1) URLs may not be used to reference interfaces that employ wide
characters;
2) URLs must generate IORs with a code set component supporting
wchar data;
3) The CORE must be changed to relax the above restrictio
