The SQL Server serialization format has a flag for this too--the H bit of the Serialization Properties byte in version 2 of the GEOGRAPHY structure.

Can we add a test serializing one of these values to make sure we match the SQL Server behavior?

Ah, I see, this is setting the flag so it gets serialized. 🤦

In that case, yeah, adding a serialization test would be nice. You can get the bytes SQL Server returns using a query like the following.

SELECT CONVERT(nvarchar, geography::STGeomFromText('POINT (0 90)', 4326).STBuffer(500).Serialize(), 2);
