Commit ID 7a6fa34f5f9f0f193d9350cd58c82a8f98a6505d

Improve compatibility this makes it easier to compile under MSVC, even though we recommend gcc/clang for production compiles at the moment. In Win32 API, by default, most null-terminated character strings arguments are of wchar_t (UTF16, formerly UCS16-LE) type, i.e. 2 bytes (at least) per character. So, src/misc.cpp should have proper type. Respectively, for src/syzygy/tbprobe.cpp, in Widows, file paths should be std::wstring rather than std::string. However, this requires a very big number of changes, since the config files are also keeping the 8-bit-per-character std::string strings. Therefore, just one change of using 8-byte-per-character CreateFileA make it compile under MSVC. closes https://github.com/official-stockfish/Stockfish/pull/4438 No functional change
