Try until no exception, leaving behind the remaining tries

Question

So I am trying to deal with an encoding/decoding error that I get sometimes. Usually it is fixed by encoding in mbcs, but I wanted to also give other situations to try for the same exception. However, I only want it to keep trying in error handling until it hits a situation without an exception.

My problem is that whether I try to use functions, multiple blocks ending with except: pass, or nested try/excepts, it always runs correctly but still gives me my final error message anyways: "'Unable to Encode most likely due to special characters.'". Can anyone help me understand how I can make the error handling stop and not continue on if there is no exception? I realize there might be better ways to do this anyways, but for a learning perspective, why am I still getting the final message and how can it be avoided if my code ran with no exception.
