[netCDF #YVO-179076]: NetCDF / nc_open / c++

We rely on various publically available libraries for our
utf-8 management (translation, normalizations, etc).

It does look like microsoft code is incorrectly treating you example
string, but I am not sure why. Is it possible to print out the two
file paths as bytes, that is in the format 0xab, 0xff,...?
That may give us a hint about what is going wrong.

One more thing, are you telling MS to use the correct encoding, i.e. UTF-8,
instead of, say, ISO-LATIN1?
