Using A Delphi Code (DICreole) with Unicode Texts

I want to use a Delphi Code called DICrole. It gets a wiki-text and convert it to HTML, RTF, Text, etc. You can download it yourself: [login to view URL] It has a demo, but the demo is very hard code. I want two simple functions to get wiki-text and return HTML and Text. The functions should be able to get and return unicode (utf8) texts.
