How to do back conversion

Question

In order to convert std::wstring to UTF-8 I use the following code:

std::wstring my_wide_string = L"my_sqlite_db.db";
std::wstring_convert<std::codecvt_utf8<wchar_t> > myconv;
myconv.to_bytes( my_wide_string.c_str() );

Now, I need to do a back conversion, ie UTF-8 to std::wstring .

What is the proper way to switch the converter?

Answer 1

Why not just use from_bytes() the reverse function:

std::wstring test = myconv.from_bytes(myutf8);
