Script is crashing game when world is loaded.

The attached script crashes the game on loading. 

I narrowed it down to new code I had installed until I used a single comment to reproduce the crash:

/* § */ 

Deleting the digraph and reloading gives a clean load. 

All my work up until had been done on gvim v8.1 x64, so I opened the file in notepad and inserted the same character and got the same result, crashing the game. I then went to VS Code, and inserted the Digraph, the game loaded and the script worked as expected. 

Finally I opened the file back up in gvim and saw an additional Digraph in front of the one we see here,(screenshot attached)

the files are marked -vscode and -gvim respectively

The problematic character is on line 17
