This macro constructs the 8 bit variant constant -literal descriptor for non-Unicode strings. The literal descriptor object -is an instance of a TLitC8 class and the macro generates const -static TLitC8 in the C++ code.

This macro constructs the build independent -type constant literal descriptor.
