Problem using a no-break space in Rise 360

Hi all,
Problem using a no-break space in Rise 360
Protected spaces are used whenever two words, characters or symbols should remain close together.
z. e.g. 5 kWh, 100 km

Set a protected space

in Word with Ctrl + Shift + Spacebar
in macOS with Alt + Space
in any program with Alt + 0160 (enter in the numeric keypad)

But it does not work in Rise 360

Any help appreciated!
