// On Windows there is a problem with non-ASCII characters in path and file names
// as far as support by the standard components used is concerned:
// The various file stream classes, e.g. std::ifstream and std::ofstream, are
// part of the GNU C++ Library / libstdc++. On the most basic level they use the
// fopen() call as defined / made accessible to programs compiled within MSYS2
// by the stdio.h header file maintained by the MinGW project.
// The critical point: The implementation of fopen() is part of MSVCRT, the
// Microsoft Visual C/C++ Runtime Library, and this method does NOT offer any
// Unicode support.
// Monero code that would want to continue to use the normal file stream classes
// but WITH Unicode support could therefore not solve this problem on its own,
// but 2 different projects from 2 different maintaining groups would need changes
// in this particular direction - something probably difficult to achieve and
// with a long time to wait until all new versions / releases arrive.
// Implemented solution approach: Circumvent the problem by stopping to use std
// file stream classes on Windows and directly use Unicode-capable WIN32 API
// calls. Most of the code doing so is concentrated in this header file here.
