It seems FxHashMap is giving machine-dependent order... I'll use BTreeMap for stable ordering.

crlf0710 · 2020-05-12T17:39:54Z

Is this ready to be r+-ed? Also cc @petrochenkov and @Mark-Simulacrum in case they want to have another look. The TL;DR is that since we can skip pure-ascii codebases now, this should no longer have compilation performance regression any more(other than a FxHashMap -> BTreeMap switch), and now i've turned on confusable_idents lint to warn-by-default.

Mark-Simulacrum · 2020-05-12T17:56:29Z

@bors try @rust-timer queue

I want to just check that we're correct that this is not a performance regression. I've not reviewed the code in any detail.

Fwiw I don't think we need to immediately update the RFC. The RFC typically doesn't even need to be updated in cases like this.

…=Manishearth Implement mixed script confusable lint. This implements the mixed script confusable lint defined in RFC 2457. This is blocked on rust-lang#72069 and unicode-rs/unicode-security#13, and will need a Cargo.toml version bump after those are resolved. The lint message warning is sub-optimal for now. We'll need a mechanism to properly output `AugmentScriptSet` to screen, this is to be added in `unicode-security` crate. r? @Manishearth
