std::format() was added by C++ 20, so, if you're using C++ 98, C++ 03, C++ 11, C++ 14 or C++ 17 this isn't available.
Also, while many modern languages will just cut to the chase, UTF-8 or GTFO, in C++ 20 strings are just containers for arbitrary sequences of values in some implementation defined encoding, so the standard can't say exactly how wide anything is, and although real world implementations probably do what you expect you're assured of nothing for this "width" specification, that's entirely implementation defined. Good luck.
