Encoded UTF8 characters do not work using the "Upload File" in File Upload

[richardhallett]

Description:
When attempting to use the "Upload File" button on File Upload nothing happens.
A Javascript error is being thrown, my initial suspect is that it because files containing non ASCII files do not properly get handled when we attempt to parse in the doi-upload.js file.
This is specifically to do with uploading the data in the file, not Fabrica's ability to create metadata with UTF8

Reproduce

1. Create a XML file that has a description with a non ASCII character e.g. ’
2. Attempt to use "Upload File" button to load this file.
3. See the JS error in console

JS Error pasted for conveniance:

URIError: malformed URI sequence[Learn More] doi-upload.js:6:11
	b64DecodeUnicode doi-upload.js:6
	onload doi-upload.js:17

Attempted to re-create for bug fixing but unable to cause the problem. Various UTF8 in a UTF8 encoded document in various fields all work as expected.
