nit: would it be possible to have System.ReadOnlySpan<byte>, too?

We could, but it wouldn't convey that it should be UTF-16 encoded. But given a ReadOnlySpan<byte>, you can readily cast to ReadOnlySpan<char> (i.e. without copying data) using this:

ReadOnlySpan<byte> bytes; // initialized elsewhere, assumed to be UTF-16 encoded chars
ReadOnlySpan<char> chars = MemoryMarshal.Cast<byte, char>(bytes);

Fair enough, thanks!

@AArnott Thanks. Is CI still configured for this repo? Looks like the last CI run dates from early October?

@qmfrederik Oh, snap. Ya Azure Pipelines triggers broke for GitHub triggers all over the place. I finally found a workaround but hadn't applied it to this one. I've fixed it and queued another CI build.
