The std::string.append function isn't a good option because it doesn't accept many forms of data. The solution is to override std::stringstream and to give it better matching operators: I have to confess I didn't measure the performance, since I have not used it in an environment which makes heavy use of string building yet, but I assume it won't be much worse than std::stringstream, since everything is done via references (except the conversion to string, but thats a copy operation in std::stringstream as well), std::string's += doesn't work with const char* (what stuff like "string to add" appear to be), so definitely using stringstream is the closest to what is required - you just use << instead of +.

This stream class is used to perform string-based operations. You can use .append() for simply concatenating strings. Reinventing the wheel. So, you must convert the string from UTF16 to UTF8 format as well, and not just convert to std::string. 1 byte header (2 bits to tell if following data is :moved string, string or byte[]), I store directly bytes of short strings (for sequential memory access), set a flag in the class if there are unused reserved bytes there. I have not required this trick with std::string or std::stringstream. I would normally reserve some room first if I know the rough size of the string in advance. Why is the C++ STL is so heavily based on templates? I used bad coding practise (opaque buffer, easy to make it not portable, I believe mine is portable by the way). I normally use either std::string or std::stringstream. Get access to ad-free content, doubt assistance and more! That's different than Java's immutable Strings in which every append operation needs to copy all characters in both Strings to a new one, so a series of appends ends up as.
