Hi Daniel, I've been using the ARC PHP libraries to query my local Virtuoso SPARQL end point. While this works fine for small amounts of data, the memory usage of paging through hundreds of pages of results is too much for my PHP process to handle. Is there a better way to do SPARQL

Hi, I think I found the issue. It was that there was one bad UTF-8 character in the whole document. That should have lead the parser to select a different encoding because of the inconsistency into the encoding of the file. When I was slicing it, I had slices properly encoded into UTF-8, and
