Looks like there is an invalid character (copyright) in the [sbe-2.0rc3.xsd ](https://github.com/FIXTradingCommunity/fix-simple-binary-encoding/blob/20df0aa1016133949b469d9976ff1ff07ad3e30c/v2-0-RC3/resources/xsd/sbe-2.0rc3.xsd#L8) file. Both `Visual Studio` and `XML (Red Hat) VS Studio Code plugin` application complain. I think `©` should be replaced with `©`
