If GetProcAddress() expects a byte string encoded to the ANSI code page,
my patch is correct because the function used the UTF-8 encoding, not
the ANSI code page. We can maybe use GetProcAddressW() to pass a Unicode
string. I don't know which encoding is used by GetProcAddressW()...
I already patched _PyImport_GetDynLoadFunc() for Windows: the path is
now a Unicode object instead of a byte string encoded to the filesystem
encoding. _PyImport_GetDynLoadWindows() uses GetFullPathNameW() and
LoadLibraryExW(). The work to be fully Unicode compliant (for the path
field, not for the name) is not completly done... but I have a pending
But this patch is huge and creates many functions. I am not sure that we
need it, I will work on this later.
