That's not the issue; the question was posed clearly enough. The problem
is that your purpose is opaque, and we have a strong suspicion your
approach is not well suited to the purpose.

Thank you for the example code. However the same issue remains:

Why is the data in such a state that you can't decide how to use it
until you know whether it is a set versus a string? Can the data be
handled differently? We'll need to know what you're trying to achieve,
to answer properly.
