Re: [dotNetRDF-bugs] Encoding problem with SesameHttpProtocolVersion6Connector and Update(...)

Thanks for reporting this, filed as CORE-374 [1]

I'm currently in the midst of relocating countries (and continents) so
likely won't get to this in the next couple of weeks but will aim to have
it fixed in early October and released as part of the 1.0.1 release

Thanks,

Rob
