@Ondřej-Šutera It does it both in Edge and in Chrome. If you type in "Frankfort KY" it works as it should. But if you navigate there with the mouse on the map, then expand, it shows the different characters.

When I go to Frankfort, Kentucky USA, the name of the city is displayed in the wrong characters from the font set. They appear to be pronunciation characters.

This is the only city that I have noticed this behavior. It just happens to be where I work.
