Warning in TurtleParser when parsing typed literals.

[12.15s] PHP Warning: Trying to access array offset on value of type int in /srv/hedgehog/app/phplib/composer/vendor/semsol/arc2/parsers/ARC2_TurtleParser.php on line 566

It only seems to happen on lines with a typed literal, and not every time that line shows up. eg. a file of 1000 identical triples:
http://id.southampton.ac.uk/building/FOO http://www.w3.org/2004/02/skos/core#notation "FOO"^^http://id.southampton.ac.uk/ns/building-code-scheme .

causes only a few warnings, not one per line

I've done some debugging and the warning is in xRDFLiteral when sometimes the value of $v seems to be truncated eg.:
string(51) " "FOO"^^<http://id.southampton.ac.uk/ns/building-co"

It feels like it's reading in blocks of data and ensuring it's got a full triple but not checking that the ^^ part is complete too?

Thanks for the report, even though I lack the time to have a deeper look. Feel free to dig deeper (+PR) and I will be happy to help.
