Subject: [PATCH] Fix of Boost 1.79 deprecated boost::filesystem::ofstream
 #8238 Replacing boost::filesystem::fstream with boost::nowide::fstream
 variants with the unfortunate cost of string path conversion on Windows from
 16 bits to UTF8 and back to 16 bits.

Unfortunately we cannot use std::filesystem yet as it is missing
on older MACs and because the interface is crooked minefield on Windows
