Can't confirm font size

[cprn]

Hi, I use Manjaro-i3. After few days I'm trying to configure fonts but when I run bmenu -> 3 Set font then choose a font and type in the size, I cannot confirm it. Tried enter - does nothing, escape - same, even tried insert - it's the only one that gives an output:

Wrong. Press any key and try again

How do I confirm the font size?

The problem lies in /usr/bin/appearance-menu function numberinput:

277     while true; do
278         read -s -n 1 schar
...
284         $'\n')   #Enter
285             break
286             ;;

You have to check for empty character instead to be compatible with all terminals:

'')   #Enter
    break
    ;;
