> It is known fact that detecting the encoding of the name/comment of ZIP entries is a messy process. And that the general purpose bit 11 is often unreliable.
> Only the so-called Unicode extra field (if present) can be trusted to reliably determine a ZIP entry name & comment, as far as I understand.
> But the current API of Commons Compress doesn't (easily) expose in which situation the ZIP archive reader is.
> That's why I propose to add a couple of new getter/setter-exposed fields to {{ZipArchiveEntry}}, e.g.:
> {noformat}
> boolean hasUnicodeName
> boolean hasUnicodeComment
> {noformat}
> This way it can be easily determined if the value returned by {{ZipArchiveEntry::getName}} or {{ZipArchiveEntry::getComment}} can be trusted. Or if it needs some "character encoding sniffing" of sorts.
> What do you think?
