XmpMetaFactory.SerializeToString returning a string with a BOM at the start?

[Numpsy]

Hi,
I've been doing some testing with reading and modifying some existing XMP, and then converting back to a string with XmpMetaFactory.SerializeToString and it appears to me as though the the returned string has a BOM at the start?

I noticed because If I try to convert the XMP to a string and then parse that straight back with XmpMetaFactory.ParseFromString then this happens:

And then the first character is this:

and if I trim out the first character then the parse works.

Is this correct?

Thanks.
