In fact, the quewstion is more, how to return that value?
By using an in/out parameter, of by changing the function return value.
I initially suggesrted the former, but thinking about it, I guess the latter 
would be better.
We could have a return value equal to the number of unconverted characters 
rather than a boolean (so zero would indicate complete converstion).
And for consistency we'd want to do the same thing for GSToUnicode()
