While today the Unicode is widely used to support characters encoding, in the past, many different 8-bit encodings were available to satisfy the needs for using national language characters. The archive programs typically were using a character encoding for file names as it was provided by the local operating system without any conversion and without even knowing what the encoding is. If you have an archive file created with one of such tools and with files using non-ASCII characters in their names, you may need to manually pick the right file names encoding. To do that, open the archive, open the options panel (press Control + o) and select appropriate encoding using the ‘File names encoding’ drop-down list.
Note, that the encoding you select for an archive is remembered by the app and you don’t have to select it again when you re-open that archive.
