Thanks. And I get compilation error in
String characters = run.characters().substring(from, to - from);
I think it is because 'run.characters()' returns a UChar* which does
not has a method called 'substring'
WebKit/WebCore/MyTest.cpp:92: error: request for member ‘substring’ in
which is of non-class type ‘const UChar*’
