How to use iconv in Qt?

I've installed qt-sdk-win-opensource-2010.03 and found an libiconv-2.dll in mingw part of qt distribution.

How do I use it (I can't find iconv.h)?

Is t开发者_C百科here a static version of iconv library?

I believe iconv library is used by Qt itself for Unicode functions. If you you are using Qt already, may as well use its Unicode functions since they are much easier to work with.
