Cool project! Something to consider: "Transformer"[1] is already used to refer to a popular element of state of the art deep neural networks, especially ones that are used on natural language, i.e. text. That might make this name a little confusing for people who have a foot in that world, especially since "Universal" and "Text" are also words thrown around in similar contexts.
