@feditips @weirdwriter A bigger problem was that my screen reader read the whole message in Swedish. There is no indication of the language used.
When I instead switched to the web page (I’m normally using an app), it read the emoji as “grinning face with smiling eyes” (but the Swedish equivalent) followed by “image” (in English), “smile” (in Swedish) and finally “smile” (in Swedish).
So the official web page of this message presents the emoji as an image rather than text. Why?
