Weird characters break markdown compilation without any error

[DominikGuzei]

After copying text from Illustrator directly into a markdown blog post example, the content wasn't parsed correctly anymore (it didn't show up in posts.node.list anymore) but there was no error message regarding invalid content/chars.

Here is the corresponding blog post content:

---
title: "Announcing Josoor Answers"
subtitle: "“The place for refugees and supporters to unite through sharing knowledge and translating information.”"
date: "August 2, 2017"
