Research direction

Description

bug

What happened?

The README template generates the following badge for the CC BY 4.0 license:

[![CC BY 4.0](https://img.shields.io/badge/License-CC BY 4.0-brightgreen)](...)

When rendered on GitHub, the badge is broken because the spaces in the Shields.io URL are not URL-encoded. It looks like this:

![CC BY 4.0](https://img.shields.io/badge/License-CC BY 4.0-brightgreen)

Replacing the spaces with %20 fixes the issue:

[![CC BY 4.0](https://img.shields.io/badge/License-CC%20BY%204.0-brightgreen)](...)
