Review Comment:
I'm a little concerned that this could be a breaking behaviour change, but I
checked that decoding is forgiving of whether or not a BOM is present,
regardless of the `encoderShouldEmitUTF8Identifier` parameter. So I think this
is OK.
I notice that we disable testing the `StringView` type in our C Data
Interface Python integration tests:
https://github.com/apache/arrow-dotnet/blob/dc2c56617f5612cfd77750ba79b21f0e9a2ec5e6/test/Apache.Arrow.Tests/CDataInterfacePythonTests.cs#L772-L773
Did you find that emitting the BOM was causing a problem when integrating
with another Arrow implementation?
