Subject: Turtle parser - escaping backslashes doesn't seem to work
Download (untitled) / with headers
text/plain 686b
As I read the Turtle spec (any version), the following should be parsed as a single character literal consisting of one backslash: "\\" However, it's currently parsed as a two character string consisting of two backslashes. Ditto the long string form: """\\""" I believe the following should work too, but it currently results in a parse error: '\\' And the following also seems to be permitted by the latest W3C draft, but was not allowed in the dajobe.com drafts of Turtle: '''\\''' The first two cases are covered by the attached test file. This is fairly important as it's blocking RDF-RDB2RDF from passing test R2RMLTC0010c from the R2RML test suite.

If you have RDF::Redland, you may need to suppress it: BEGIN { $ENV{RDFTRINE_NO_REDLAND} = 1; }
