I think that the best practice is to validate input.
Besides the overhead of revalidating there is the issue of what do you do
with data that contains invalid characters. This has to be handles
explicitly. Once validated all transforms should maintain valid data. If
you also provide a modified strncpy function that returns a length instead
of a pointer and only copies complete code points in whatever UTF you are
using you should not break the validity.
