How do I write the name A*PA in obsidian?

It’ll render in reading mode, where I checked it. But not in live preview?!

Hmm… it’s already a feature request:

Render HTML Entities in Live Preview

Use case or problem HTML Entities are very useful for inserting symbols, for example I frequently use them to insert arrows (→, ⇄) or greek letters (α, γ, θ) into my notes. They are rendered in “Reading View”, but not in “Editing View” with Live Preview mode, which is a shame. Proposed solution HTML Entities should be rendered in “Editing View” with Live Preview.
