What might be causing question marks to randomly appear in product descriptions and elsewhere?
As an example:
We carry a range of?different French and Italian cheeses. Due to their fragile nature, and their requirement for expensive refrigerated couriering, we?only sell these in-store.
Epoisses, Brebis papillon, Bleu d'Auvergne, Brie de Meaux, Chevrot, Comte, Fourme d'Ambert, Laguiole, Livarot, Maroilles, Mimolette,?Morbier, Munster, Pierre Robert triple-cream brie, Raclette, Le Sarlet, St. Marcellin, Tomme de Brebis.
I've marked them in red. I can't quite see how they're getting in there. It's not my typing, and the client is not dumb; he's not leaning on the question mark key and from the content and the fact that it also happens on menu items occasionally I'd say that it is not caused by pasting in formatted text.
Any ideas are much appreciated.
