No way to set the source encoding when using Paket Pack

I'm receiving an error when pushing a nuget package to my Nexus repository. This package is built using Paket Pack output ./. I use the exact same command on other packages, and there are no issues. After some research I've narrowed it down to the error below; ZipException invalid stored block lengths. Which seems to be associated with the source encoding. I see that paket supports preserving nuget's source encoding when converting a nuget package, but I do not see anything for specifying it when packaging.

It would be nice if we could specify the encoding in the package template and/or on the command line.

Error:

Reproduction steps:

1. Make a package from here: https://github.com/amplitude/unity-plugin/tree/master/Assets
2. And attempt to upload the package to a nexus server ~v2.12.
   Note: Unzipping on the command line seems to understand it fine.

Thanks!

Start with the Paket Pack command and the existing source-encoding preservation behavior used when converting a NuGet package. Check how package templates and command-line options are parsed, then reproduce the upload against Nexus v2.12 using the linked Unity package. Done means an encoding can be specified through the template or command line and the resulting package is accepted by Nexus.
