What happened?

If the copyright string has < > in it like on heatingcontrol readme <2019-2021>, they can't be opened while it crashes.
Click on the link to see only a white page.
In the browser console is a message that says "The tag name provided ('2019-2021') is not a valid name." here we see the copyright year string.

It also had the brackets around the email ...

I proposed at least a fix as temp workaround rg-engineering/ioBroker.heatingcontrol#315
