Literals with \ cause index build to fail

[Qup42]

After #1361 (9e8cc07) was merged the build of the WikiData index broke for me. The problems are also present on master (currently 14d6e1c). The AD_FAIL on line 145 of src/parser/RdfEscaping.cpp is being triggered by literals that seem to contain \displaystyle.... Could the changes to TurtleParser from the mentioned PR be related to these problems?

One of the triples that seem to cause problems is

Can you try building the index again including PR #1392 to confirm that this fixes your issue?

[Qup42]

I can confirm that it fixes the issue when applied to my working branch.
