Why don't my markdown titles work sometimes?

This technical blog post investigates a common Markdown formatting issue where headers fail to render correctly. The author identifies the cause as accidentally typing a non-breaking space (Unicode \xa0) instead of a regular space after the hash symbols, often due to Mac keyboard shortcuts. The article includes examples, a Python code snippet to demonstrate the problem, and explains how different tools (GitHub, Obsidian, Hugo, etc.) are affected.
