Problem with special characters! Need a big help!

Hello!

Please be patient with me. English is not my main language.

I have a big problem in Adobe Dreamweaver CS4 with my countries special chars.
Our spec. chrs are á,é,í,ó,ö,ő,ú,ü,ű

When I save a document every other characters (even other special chars) are okey, but Q and q will be o and u after saving my document.

This is really annoy me. I've read a lot of forums in my country, but I can't find any solution.

When I go to "Edit > Preferences > Fonts" and no document is open, Font Settings: Unicode
If I change this, and I reopen this window it will be on Unicode again. I can't change it.

When I go to "Edit > Preferences > Fonts" and my documents are open, Font Settings: "Nyugat-európai" (means Western European)
If I change this, and I reopen this window it will be "Nyugat-európai" (Western European) again. I can't change it.

It should be: "Közép-Európai" (means Central European) but every time I change it, it reverts to this defaults.

Please help me!

I have to reopen every file in Notepad and rewrite the &#337,ű chars.

Thanks!

EDIT: EE can't display correctly these two characters either...
