The first sentence of your post said you wanted to convert Windows
Unicode to UTF-8. Can you really blame him for interpreting your
question differently than you meant? He was trying to be helpful.

Anyway, the following does (I think) what you want. It specializes on
int* instead of wchar_t*, however. Minor detail. I'm sure you
understand the idea. Use the template on the function, not the class,
then provide a specialization.

    template <typename T>
        IConvPtr& operator=(T aptr) {

int main() {

    c = &b;
    cout << (void*)c << endl;

    c = &a;
