I only use ascii functions where there are no UTF-8 functions. For
instance, split().

I have attached a text file (ODT) as well as the code itself. Note that, in
order to run the code you will have to have unoconv installed.

If you comment the two lines bellow, the code will not work.



* RawText = RegExp.Replace(RawText, "À", "à") RawText =
RegExp.Replace(RawText, "Ó", "ó")*

This happens because for some mysterious reason, the QT library seems to
get confused
with *À* and *Ó*. But not always!
