  If performance matters most, write your own specialized string processing code which works on "raw" data in memory buffers. If convenience matters look at https://github.com/fmtlib/fmt https://github.com/fmtlib/fmt (or std::format which AFAIK is less feature rich) and https://github.com/imageworks/pystring https://github.com/imageworks/pystring.
