I just edited the file: auto_anchor-article.dat, for example from English to Portuguese.
I did a test with an article to get the preview – minimal, and the article shows strange symbols, see image.
Those symbols are shown in the article.
I think it’s because of the accents.
My question is: will these symbols appear at the end of the campaign (articles, webs, wiki …) or does it only show in the preview?
