What is this marking please?

No idea. I wonder if there's some incompatibility between the "special symbols" in your pdf reader and the format in which the document was produced.

I somehow suspect this as well - it isn't a musical symbol and judging by the screenshot you gave us, is it a score from Musescore or one of those free sheet music place?

Thank you for your replies, now you have put my mind at rest, I shan't worry. It may well be some weird printing error.

Have you looked at other editions/sources to see what notation should be there?  This was probably a poor printing transcription  of a real notation.
