How to convert back from utf-8 to the "standard" character set

I am having some problems with parsed xml files. The parser insists on
returning the text encoded in the file as utf-8. Result is that accented
characters in the encoded text shows up in the wrong encoding on screen. How
can I convert these strings back so I get the proper accented characters on
screen.

Are there any conversion functions available in Dolphin or maybe a win lib.
