Yes, I think you should just try importing the data (reading the CSV), 
this is probably where things break. Then try also with a small trivial 
variant of that CSV, ensuring it only has ASCII characters, as a sanity 
check. So in other words, creating a minimal reproducible example. This 
can be an encoding issue, for instance.
