Emojis silently generate empty blog post

[MattiooFR]

Environment

Python Version:
3.11

Nikola Version:
8.2.3

Operating System:
MacOS

Description:

If there is an emoji in the posts content, the html will silently not be generated when I do nikola auto or build.
It was working before so I don't know what changed and make it not work.

My blog posts are done using pandoc in markdown.

This is an example that doesn't work :

<!--
.. title: test
.. slug: test
.. date: 2023-04-24 18:59:18 UTC+02:00
.. tags:
.. category:
.. link:
.. description:
.. type: text
-->

I cannot reproduce using pandoc and Markdown, and using reST, on Linux.

1. Can you reproduce in a clean demo site using reST, python-markdown, and HTML?
2. Is there any content in cache/posts/test.html?
3. Do you get any error output when you run nikola build -a -v 2?
