Custom file encoding and extension.

[EmiliaZorin]

Hi!
I am working with Cypress and having some issues. My goal is to drag and drop a certain file, that it`s encoding is not supported, to a droppable element.
Is there any way to make the encoding and the file extension flexible to receive other types then the ones that are mentioned in the bundle.js?
I mean something lime this:
cy.get(someDropZone).attachFile( {filePath:'path/to/file.someExtension',encoding:someEncoding} , { subjectType: 'drag-n-drop' } )

If you have other suggestions I will be glad to hear! Thanks!!
