Yeah, probably should have made a more substantive comment. I'm mostly thinking of the trio of Skrifa, Harfrust, and Parley, but there is other open source Rust work that qualifies as well.

There's also, very relevantly, the DWriteCore work from Microsoft. My understanding is that there's been some talk of open sourcing that, but it's still proprietary.

There are other things that count as high performance text in memory safe languages, for example implementations in Go, but in general those are not a good candidate to replace C and C++ in environments like operating systems and browsers.
