Meta keyword "hugo" not possible?

I’m just playing around a bit with my page and edit the meta-tags.

Is there a real reason for not being able to set “hugo” as a keyword in my config.toml? It works without problem in content-files.

Using Hugo v.15 on Win 10 x64

There are some Hugo Variables. They look like .Hugo.Generator. Maybe that’s the reason.

A possible workaround to add hugo as a keyword in your meta-tags is the use of unicode-escaping.

keywords = "\u0068\u0075\u0067\u006f"
