unknown character/glyph - black diamond with question mark inside

[biek]

I am frustrated, every time i go to new line i press enter and that's should work in catalog. But in the product page (FO) there is always this black diamond with question mark inside instead of empty line.

I had problems with some other characters as well, but only in footer, so i changed them with HTML codes

€ = €
and so on...

and so on for čžš.... i am frustrated please help. I am using slovenian language, but it is the same if i change to any other.

And product descriptions, where the problem exist were copied from previous shop.
