Heh, "acentos" (marked vowels) aren't used in english, but yes in other languages like spanish or portuguese. I had them in my title and location, but the text got corrupted at some moment (don't know why), so I had to edit them. But now I see some letters aren't showing correctly.
Vowels: a e i o u
Marked vowels: á é ß ó ú
As you can see, the marked 'i' isn't displayed right. Why is this? This didn't happen before.
