Nope - in all cases it's not the character that's marked red but the small
rectangle symbol a few characters to the right from the red ones.
For example this one, where the "i" in Bishop's is marked red:

Line 235, column 56898: non SGML character number 146
...link">C28 Marriage difficulties and Bishop’s Visitors</a></li><li><a
href="i
                                                                  ^^^
And - yes - they can be incorrect even though TYPO3 is not producing them.
You hardly can see the difference but there is one:

              '                      !=                     '
        incorrect                                    correct
        char 146
"curly" apostrophy         !=      "standard" apostrophy

If this is coming from your keyboard by default, you should change the
keyboard layout and/or language settings.
