Special characters in heading / front matter

How can I include a colon in the title of my article, without getting “Error: Invalid Frontmatter …Unexpected characters…”? I have

title: "6:07am Sharp" for Orchestra

But the colon throws the error. Is there a way to escape the character?

The front matter is basic YAML. Those docs will explain all the various escaping options. In this case, just enclose the entire title in single quotes.

Perfect, thanks!
