Hi Sascha and list,
the signs fort he Umlauts differ whether you are using six-dot or 8-dot braille.
I usually don’t use braille input so would have to research the exact braille signs myself.
From your description I would guess your braille table has been set to 8-dot braille which is the normal setting for computers.
You could do two things here: try to set the braille table to six dot braille.
- Input the umlauts in 8-dot braille.
Hope that helps to see things a bit clearer.
