Hi RainRider!
I'll try to describe my problem again. I see that
your SpellBooks addon is working fine

. Still,
mine is not. Umlauts just don't show up. Instead a "?" or a "BLOCK" is displayed and so Items like the "Totem der Erdstärke" are not recognised by the addon. I had the same error with the "ItemSets" addon first. This has been solved by replacing all the umlauts in the deDE.php of ItemSets with their UTF-8 charakters (like "ä" for "ä"). Naturaly I tried the same for SpellBooks, but somehow that didn't work. No matter if I replace the umlauts myself with any editor (tried windows notepad, phase5 HTML editor and Notepad++ with UTF-8 encoding) or use your SpellBooks deDE.php, umlauts just won't show. :-(
I'm not that much into all that text formats and webserver stuff so maybe the mistake is on my side and very obvious to someone with deeper understanding of such things.

I'll try setting up SpellBooks
again later today, with your deDE.php from the begining, not replacing the old one.
