[Wikidata-bugs] [Maniphest] T292659: RDF engine does not support some strange characters?

  In your specific query, I suggest removing the `DISTINCT`: in combination 
with `GROUP BY`, it makes no difference.
  
  More generally, this is likely an Blazegraph limitation. I don’t know if 
there’s still an upstream that we could even report this to (the Jira that I 
find in my history seems to be dead).

  It looks like the issue is just `SELECT DISTINCT` on sufficiently long 
strings of any kind. Query 
:
  
SELECT DISTINCT ?a32768 {
  BIND("a" AS ?a1)
  BIND(CONCAT(?a1, ?a1) AS ?a2)
  BIND(CONCAT(?a2, ?a2) AS ?a4)
  BIND(CONCAT(?a4, ?a4) AS ?a8)
  BIND(CONCAT(?a8, ?a8) AS ?a16)
  BIND(CONCAT(?a16, ?a16) AS ?a32)
  BIND(CONCAT(?a32, ?a32) AS ?a64)
  BIND(CONCAT(?a64, ?a64) AS ?a128)
  BIND(CONCAT(?a128, ?a128) AS ?a256)
  BIND(CONCAT(?a256, ?a256) AS ?a512)
  BIND(CONCAT(?a512, ?a512) AS ?a1024)
  BIND(CONCAT(?a1024, ?a1024) AS ?a2048)
  BIND(CONCAT(?a2048, ?a2048) AS ?a4096)
  BIND(CONCAT(?a4096, ?a4096) AS ?a8192)
  BIND(CONCAT(?a8192, ?a8192) AS ?a16384)
  BIND(CONCAT(?a16384, ?a16384) AS ?a32768)
}
  
  With `SELECT ?a32768`, or with `SELECT DISTINCT ?a16384`, the query still 
works.
