Language Error

Hi

I have a critical error that I need to get answers to.
I am using this HTML component for a scrolling banner on the bottom of the screen:
http://www.kfc.is/assets/HTML.html
However your software does not seem to be supporting my language (Icelandic)

Can you please help finding a solution to this matter, otherwise this software won't be possible to be used.

Thank you in advance.
