It is a symbol in negative (i.e. white font on a black background (I have attached 2 screen snippets, the second one a 500% enlargement, as example).
Can ANYONE explain such a weird symbol. I have never encountered it elsewhere and can find no information of it online.
[P.S. Sorry if I have posted this in the wrong forum section, I wasn't 100% sure.]
