What I mean is this: If you *already have* a module that converts between TC and SC, using a DBCS encoding, and you are satisfied with the results, then it would be possible to modify such a converter to use Unicode instead of the DBCS. The data in Unihan.txt can assist you here. If you *do not* have a satisfactory TC/SC conversion routine, then switching to Unicode will not get you one, because the Unicode and ISO/IEC 10646 people have very wisely decided not to get themselves tangled up in that cobweb. You need to define (or explain) what you mean by "implementing Unicode." If it means converting your input data to Unicode from GB 2312 or CNS 11643 or Big Five or whatever, that's fine. But don't be misled, Unicode support does not in any way imply support for TC/SC conversion.
