What is state of the art: Unicode file names on Windows

Some files are mixed text/binary/base64, so you may need to extract text components before you are trying to guess its encoding.

The only way that mixed content can be handled reliably is if the binary data is base64 encoded. Then the whole document is utf-8 encoded.

@lassoan

These should be all doable, but requires some effort. You cannot ignore the file content.

In general yes, but I was referring to the file readers listed by @efahl in my comment.
