Finish 1.0.9
Pass options to Kernel.open in Util::File#open_file.
Added RDF::URI::NON_HIER_SCHEMES used to implement #hier?
Make #root? of a non-hierarchical URI return true, so that #parent of a non-hierarchical URI will always be nil.
This addresses issue #130.
Fix issue with open_file
Mostly use #encode! instead of #force_encoding.
When checking for formats, ensure that everything is encoded as UTF-8.
Change encoding of all literal strings to UTF-8.
Finish encode
When escaping strings, ensure that intermediate has appropriate encoding, so we don't double encode.
Make sure inline strings are all encoded as UTF-8.
