or in Jerboa

Hmm, but the best part about markdown is that it is human readable regardless so it should still be fine

Nor Boost. It does in Raccoon, though.

Renders in Summit, but I turned that off because any post title starting with # is rendered as h1.

Or Thunder

Renders fine in Sync

I mean, code could work and maybe ^superscript^ or ~subscript~ and that’s about it I think

    "markdown-it-sub": "^2.0.0",
    "markdown-it-sup": "^2.0.0",

I think it's fine to use unique platform features like this, but if you're actually using this actively, be aware that not everyone will see your titles as you intended them. It's only Lemmy users that can see it actually render "properly", everyone else just sees the plaintext Markdown symbols.

Do you know a way to see the ActivityPub JSON for fediverse objects?

In the ActivityPub JSON for this post, there is no indication that this field contains MarkDown. …. it says it contains HTML

This seems like a bug. Regardless of what clients may support, the json ought to accurately describe fields

In the ActivityPub JSON for this post, there is no indication that this field contains MarkDown. If anything, it says the opposite, it says it contains HTML. It’s therefore not unreasonable for other platforms to render it as such.

Actually, the name property is explicitly plain text, it shouldn’t contain any type of markup, whether that be markdown or HTML.

Also, this gives me real text-on-image-in-Facebook-post-just-to-get-noticed vibes.

If everybody can use Markdown in their post titles, then everybody will use Markdown in their post titles, until it’s a mess of colors, bold, and italics.

Markdown is plain text, so it’s fine to go in the field. It’s also fine for apps to allow OP’s post to look like garbage because there’s no requirement for support.

ABSOLUTELY NOTHIN

Do you also have the Android weirdness in which the tick marks appear to be in a different place? (Not Jerboa-specific)

Sync for lemmy works

Guess it depends on your client because it works for me.

What client do you use?

Oh no indeed
