Handle with test file:

@prefix show: <http://example.org/vocab/show/> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

show:218 rdfs:label "That Seventies Show"^^xsd:string .            
show:218 rdfs:label "That Seventies Show"^^<http://www.w3.org/2001/XMLSchema#string> . 
show:218 rdfs:label "That Seventies Show" .                                           
show:218 show:localName "That Seventies Show"@en .                 
show:218 show:localName 'Cette Série des Années Soixante-dix'@fr . 
show:218 show:localName "Cette Série des Années Septante"@fr-be .  
show:218 show:blurb '''This is a multi-line
literal with many quotes (""""")
and up to two sequential apostrophes ('').'''^^xsd:string .

And in parse result, (""""") is convert to ([\, "][\, "][\, "][\, "][\, "]) to avoid parse exception (petitparser seems to only accent one pair of " in one literal).

This does not seem to work in my testing? example_7.dart file does not parse the turtle content as expected. Am I doing something wrong here?

Can you parse the result?

All works well on Windows. It would be good if we can test this on Linux as well

Thanks @anushkavidanage, it has been tested on Linux and works well.

I have the following two observations:

Hi @srodriguez142857, made updates accordingly

Hi @zheyxu.

The output looks compliant with the Turtle spec: Quoted Literals section.

It would be ideal to have a thorough check of the syntax production rule for the [17] String.
However, as for now, the update is complete and serves our purposes.

All good.
