How to parse with rapidjson from std::string ? I am trying like (json string is valid, I checked on jsonlint.com)

Document document;
char * writable = new char[contentString.size() + 1];
std::copy(contentString.begin(), contentString.end(), writable);
writable[contentString.size()] = '\0'; // don't forget the terminating 0
std::cout<<writable<<"\n";
if (document.Parse<0>(writable).HasParseError())
    return 1;

contentString is my json std::string, but when I start I always get error ( return 1). I tried also without size()+1 and '\0' but nothing (desperate measure programming). Can anyone help me ?
