How to write a std::string to a UTF-8 text file

Question

I just want to write some few simple lines to a text file in C++, but I want them to be encoded in UTF-8. What is the easiest and simple way to do so?

Answer 1

Use Glib::ustring from glibmm.

It is the only widespread UTF-8 string container (AFAIK). While glyph (not byte) based, it has the same method signatures as std::string so the port should be simple search and replace (just make sure that your data is valid UTF-8 before loading it into a ustring).
