dzonia lite language problems

I have a page made with dzonia lite. The page uses spanish language, so I had problems with characters like “ñ” or “á”. I wrote to you and you solved my problems deleting some lines in “custom.js” archive. It runs correctly, until I actualize wordpress to 3.5.1 version. The same problem occurred again, and I don’t know how to solve it. The “custom.js” archive seems to be ok. What can i do?

Thanks

Daniel
