It rather depends what you want to do with the text you are processing. Half the point of UTF-8 is that you don't need to change existing code if it handles 8-bit chars and does nothing special with characters above 128. Of course, strlen is the length in bytes rather than the character or code-point count.

To quote the Unicode Standard, version 5.2, chapter 5:

I would also encourage the programmer to use the TCHAR versions of the library functions, which convert to UNICODE or Ansi based on the project settings.

If you are using Visual Studio then make sure that your Project -> Properties -> General -> Character Set has Unicode selected. Then you can use all the Unicode versions of the string classes, and use the L prefix on your Unicode string constants like:

C++

wstring myString = L"Hello, World! \u2639";
