There are several problems with _msi.FCICreate() used to create the CAB file. It encodes the CAB names and added file names to UTF-8 and then use them as encoded with the local encoding. So you cannot create a CAB file in a directory with non-ASCII name or add files from a directory with non-ASCII name. This is a Python 3 regression.

Two possible solutions:

1. Encode paths with the locale encoding. It will add support for paths encodable with the locale encoding.

2. Encode them to UTF-8, but use a wrapper for opening file which converts the path from UTF-8 to UTF-16 and uses the Unicode variant of _open(). It will support arbitrary names.
