Hello,

While porting some Microsoft C++ code to the Linux platform, I have realized that while there is snprintf() function for std::string, there is no direct equivalent for std::wstring.

Do you think such a function could be added to the standard? It would make std::wstring a more viable alternative to std::string.

On the other hand, with Windows starting to support UTF-8 programs as of 2019 (and UTF-8 std::string), std::string might become a simple way to store unicode text in cross-platform programs.
