Thanks again Pinoc,
After changing my KDE to the 'old-style' the diacritics was fine in the documents I needed to edit - but all the diacritics I use in filenames in my system and so was then messed up - so I changed the necessary files (used iconv to change to utf-8) and went back to the 'new-style' (whatever that is :-). The files I changed has kept the UTF-8 encoding and show the diacritics fine as expected,
looked at utf-8 in wikipedia, it's 1-4 bytes long, and can include byte-order-mark and other peculiarities - but no description about any 'old versus new' encoding style - still trying to figure this out,
cheers,
MBantz
