As i have received a couple of questions, i decided to create a faq:
Special letters (like ü in german, é in french) don't show up or are not shown correctly
This is a Cufon problem and should be solved with changing the Cufon setting in the theme panel (set it to Disabled or Extra).
Am i allowed to change the code?
