If this is an
English title, please note that it is "objective", not
"objetive", before you have to change it again.
Boris Steipe, thanks. It's a brasilian portuguese title.
Yes. Visit all of them, edit the page and change the title to whatever
you want.
For an automated solution, use a bot, like a pywikibot. It's a matter of
doing a regex substitution.
Thank you Platonides. I've meant as automated solution, because it is a
quite big range of pages. I do not know this pywikibot. Could you say more
about it?
Best regards
Nevio
