Me too...I’m seeing an a with a caret, a weird e and tm for apostrophes in some articles. Happens on two different computers so I know it’s not me.
Betting it will do it again in your text I quoted.
Seems these odd characters are a difference between western character set (Windows-1252) and Unicode (UTF-8), often when cut and pasting text. The odd thing is they only showed up a few days ago. Can't recall seeing them prior to this.
Hope it gets cleared up soon.
