I think some of this is locale-specific, which is why it isn't obvious.
i.e., what actually happens can vary from locale to locale. For example,
é can be uppercased to E and É depending on which region you are in. See
for some stuff.
Just putting "use locale;" in your script might be a good place to start.
All the best
