What did you do (e.g., steps to reproduce)
In post front-matter, I did not surround tag containing ? with quotation marks in an array. This worked locally, however, GitHub Pages silently ignored these posts, without raising any error.
I'm not sure if other non-alphanumeric characters will cause the same behaviour (! worked fine). It's not clear which characters are considered special.
It doesn't matter whether it's tag: or tags:, but seem to only happen when an array is used.
What didn't work:
---
layout: default
title: Will it work? No Quotes
tag: [but-why?]
---
What worked:
---
layout: default
title: Will it work? No Question Mark in Tag
tag: [but-why]

layout: default
title: Will it work? Quotes in Tag
tag: ["but-why?"]

What did you expect to happen?
All three front-matter successfully generated pages locally, but only the first two were built by GitHub Pages.
Locally generated index:
Will it work? Quotes in Tag
Will it work? No Question Mark in Tag
Will it work? No Quotes
What happened instead?
Index on GitHub Pages:
Will it work? Quotes in Tag
Will it work? No Question Mark in Tag
Interestingly, when viewing the markdown file of post that was ignored on GitHub, the front-matter is formatted as a code block instead of the usual table.
With quotation marks:
