I have to confess that this is nonsense. The filenames are stored in the zip file in UTF-8 encoding. You can verify this by opening the zip file in a HEX editor and inspecting the filenames. When the files are unzipped the encoding of the filenames depends on the settings of the unzipping program and the OS. 7-zip under windows encodes them by default as UTC/unicode.
