There is a K and many posters have confirmed that on this thread! You, Sir, are a minority of one on this particular point.
Not by my tally on this thread.
It is a “K” clear as can be on the 6th level of ZOOM on my Mac Preview application, while everything around it is unreadable.
We’ll have to disagree on this one. Many other posters have confirmed it is a “K”.
Have a nice day.
