You can convert it to some encoding that you can dump as char* such as
latin1 or utf8:

String characters = run.characters().substring(from, to - from);
CString charactersUTF8 = characters.utf8(); // Or .latin1().
std::cout << charactersUTF8.data() << std::endl; // Print the results
but you can use a stream to a file or fwrite as it as char*.

If you want to avoid encoding conversion or the overhead of creating a
String and a CString, you will have to look at  the ICU documentation
(though you could use the same magic as in
http://source.icu-project.org/repos/icu/icu/trunk/source/samples/ustring/ustring.cpp
to dump your UChar*).
