Whitespace trimming Formatting a string sprintf style Conversion from utf-8 to utf-16 or vice-versa For most of these, you will have to either write your own functions, or convert your string to a C-style string (using c_str()) and use the C functions that offer this functionality. In...
Class template std::basic_format_string wraps a std::basic_string_view that will be used by formatting functions. The constructor of std::basic_format_string performs compile-time format string checks unless the constructor argument is returned by std::runtime_format(since C++26). ...

std::to_stringrelies on the current C locale for formatting purposes, and therefore concurrent calls tostd::to_stringfrom multiple threads may result in partial serialization of calls. The results of overloads for integer types do not rely on the current C locale, and thus implementations gener...
