You don't, it's the distance of the iterators in *characters* on the 
trunk -- and UTF-8 build doesn't exist in 2.8, so I assumed you're 
talking about the trunk. It's the number of bytes only in 2.8's ANSI 
build and that's because it didn't make the distinction between bytes 
and characters.

Once again, no.

No, I meant 2.9.0 -- the first development release before wx3.

You never defined what exactly you want. The length in characters is 
length() and that's what you seemed to want. If that's not the case 
and you do use embedded NULs (because otherwise it's trivial: just 
use strlen() or wcslen() on mb_str() or wc_str() return value), then 
you can for example get raw wchar_t* data:

  const wxWX2WCbuf data = str.wc_str();
  size_t dataLen = str.length();

(this is compatible with wx2.8 too; and it works because 
wxString::length() equals the length of wchar_t* representation of 
the string)
