How to get started with ICU in C

I need to handle unicode strings in C. I have heard that ICU is the appropriate set of libraries to use but I am not having any luck getting started.

So my question: Can anyone provide a link to a good beginn开发者_如何转开发ers tutorial on using unicode strings with ICU in C

P.S. I have installed libicu44 (under Ubuntu 11.04).
