Turtle syntax error v5.1.1

[wouterbeek]

Observed

The RDA Turtle files still contain syntax errors, for example "\p" is not a legal backslash escape sequence in Turtle 1.1:

Expected

RDA Turtle files to be syntactically correct / follow the W3C standards.

Additional remarks

Feel free to use https://triplydb.com to test for the syntactic validity of RDA files. We follow the standards strictly, so an valid upload to TriplyDB should imply correctness of the files.
