Colon in title in YAML header block

Colon in title in YAML header block

[R (Chandra) Chandrasekhar]

Is there any way to include a title with a colon in a YAML header block 
like so:

---
title: This title: has a colon
---

Is there a way of escaping the colon, or is this an absolute 
restriction, implying that titles with colons have to incorporated by 
other means?

Don't you quote it like any other string literal?

    ---
    title: "This title: has a colon"
    ----

That's always seemed to fix escaping problems in my Hakyll files' metadata.

Thank you. Both single and double quotes work.

I do not know YAML well and think that I had been overly fixated on 
backslash escaping to consider alternatives.

The Wikipedia page on YAML contains very good descriptions of the syntax,
both terse listing of syntax rules and more explanatory.

https://en.m.wikipedia.org/wiki/YAML

Note that some of the more advanced features don't make sense in Pandoc
metadata and/or are not supported by the parser Pandoc uses.
