Great, thank you for this information. Nice to see an expert on the list :)

Strange then that the info-zip so often creates garbled filenames on Linux !
Probably the used zipper doesn't use the extra fields. If it isn't there, infozip cannot use it obviously.

Since it is optional, we can probably add a WideString property to the zipitem and add an overloaded call;
Then we don't need to recreate everything, just add the extra fields.
