annotate Python/import.c @ 65418:fd5135cbd928

_PyImport_FixupExtension() and _PyImport_FindExtension() uses FS encoding * Rename _PyImport_FindExtension() to _PyImport_FindExtensionUnicode(): the filename becomes a Unicode object instead of byte string * Rename _PyImport_FixupExtension() to _PyImport_FixupExtensionUnicode(): the filename becomes a Unicode object instead of byte string
