That code point is U+0D9E SINHALA LETTER KANTAJA NAASIKYAYA. It’s a letter in a writing system used in Sri Lanka.

1. Why does it say where T: Sized for references &T? A reference can definitely point to an unsized type, e.g. &str.

I think the point being made is that the layout shown only applies for Sized T. Layouts for &[T] and &dyn Trait are shown elsewhere on the sheet. &str is noted under &[T].

Edit: although, similar considerations would apply to other pointer types, but that isn’t noted on the sheet except for Box<[T]>

Well, the good news is that according to this list, your instance already blocks Threads.

I can understand why people wouldn’t specifically talk about the fediverse on other sites. It just seems like there is a lot of coverage of X and Meta in the news, but there doesn’t seem to have been even a passing mention of fediverse sites in most of what I’ve seen. I guess the more established social media sites are still a lot more significant than fediverse alternatives though.

What’s sad is that people aren’t talking about Mastodon nearly as much as they are talking about Threads and X. It just doesn’t seem to get much publicity outside of the fediverse.
