In [this post](https://forums.swift.org/t/more-representative-string-benchmarks/18793/1), the following lines can be found:

However, after selecting this and clicking “Quote”, the text that appears quoted in the new post is:

Two things are very different: the side-by-side quote blocks have been lost, and the emoji have been turned to ghosts. I don’t know exactly what is involved in causing this, so I am going to post a few different versions to test with:

[details="Testing"]
<table>
<tr>
<td>

> 1️⃣

> ∀ 👤 ∈ 👥,🤰➡️👶: 👤 ∈ 🗽
> 👤 ≡ 👤: {🤝,📜}
> 👥 = {👤 | 🧠, 👼🤔👿}
> 👤 ∼ 👤: 👬👻

</td>
</tr>
</table>



> 1️⃣

> ∀ 👤 ∈ 👥,🤰➡️👶: 👤 ∈ 🗽

> 👥 = {👤 | 🧠, 👼🤔👿}
> 👤 ∼ 👤: 👬👻


1️⃣

∀ 👤 ∈ 👥,🤰➡️👶: 👤 ∈ 🗽
👤 ≡ 👤: {🤝,📜}
👥 = {👤 | 🧠, 👼🤔👿}
👤 ∼ 👤: 👬👻


👬 abc 👻
🧠 def 👼

🤝 ghi 📜
[/details]

Edit: It appears that the double line break (between “1️⃣” and “∀”) is involved with the emoji issue. When quoting text that includes multiple emoji in a paragraph (counting single line breaks as continuing the same paragraph) and a double line break somewhere in the quote, it seems that all emoji in the paragraph are replaced by the last emoji in that paragraph.

For reference, here are the plain-text “raw” versions of the [linked post](https://forums.swift.org/raw/18793/1), and [this post](https://forums.swift.org/raw/18796/1).
