In this post, the following lines can be found:

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

∀
∈
All human beings are born free and
equal in dignity and rights.
They are endowed with reason and conscience and
should act towards one another in a spirit of brotherhood.
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:

Edit: It appears that the double line break (between “” 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, and this post.
