Resolution Note:
After internal discussion we are classifying this issue as a feature request. Unity does not support the Windows long path prefix historically. We intend to support this at some point, but it will involve a larger effort than a bug fix. We'll need to ensure all file related APIs and code paths can handle this (and are tested).
