Writing to file in utf-8

Another possibility could be, after all processing is done for
each xml tree, to replace all weird unicode chars like "Été"
by its equivalent ("é" in that case) before saving to the final file...
It's not very elegant and a rather brute-force approach but it
might work, except that there's no guarantee that the final file
will be in utf8 format...

Again, any wise suggestion is welcomed...
