> Set MSVC source and execution character sets to UTF-8 to enable Visual C++ to compile all source files regardless of the active code page on Windows. This avoids build errors due to "warning C4819: The file contains a character that cannot be represented in the current code page (932). Save the file in Unicode format to prevent data loss"
