If I create a Wiki with a name that uses a letter á (like Referencia matemática) I have problems. The main page works sometimes but not always. Sometimes you get an empty page. If you click edit then you see everything. I have noticed that in the URL Moodle sometimes writes ?Referencia+matemática (when it works) and sometimes ?Referencia matemática (with a space between words when it does not works).
Other characters like í do not seem to have problems. Any idea?
