Hi,

I have not looked but what is a symbol like this meaning: "Gg7d4". It's not a notation I am familiar with.

OK so quick research, I can see that %cal and %csl is an extension that is not in the PGN spec. Here's some info I dug up on it quickly, https://chess.stackexchange.com/questions/18402/pgn-with-arrows-and-circles. I'll take a look and see what a reasonable approach would be to dealing with this, but I would assume its some variant of ignoring it or just reading it into a string since its just arbitrary extension data, not actually part of spec.
