*
* Pre-Merlin/J2EE 1.3 JavaSoft ORBs listed ISO646 for char and UCS-2 for wchar, and provided no conversion sets.
* They also didn't do correct negotiation or provide the fallback sets. UCS-2 is still in the conversion list for
* backwards compatibility.
*
* The fallbacks are UTF-8 for char and UTF-16 for wchar.
*
* In GIOP 1.1, interoperability with wchar is limited to 2 byte fixed width encodings since its wchars aren't
* preceded by a length. Thus, I've chosen not to include UTF-8 in the conversion set for wchar data.
