Double-byte character considerations
If you are using an ORB that supports CORBA later than version 2.0, you do not have to do
anything to support double-byte characters. Strings and characters in ColdFusion will
appropriately convert to wstring and wchar when they are used. However, the CORBA 2.0 IDL
specification does not support the wchar and wstring types, and uses the 8-bit Latin-1 character
set to represent string data. In this case, you cannot pass parameters containing those characters,
however, you can call parameters with char and string types using ColdFusion string data.

The following code example shows the IDL for a CORBA object that raises an exception defined
