Replace Off / 0 state with appropriate symbol

[discip]

In this PR #1678 I replaced the Off or 0 text for all corresponding menu items with the following icon:

to reclaim some screen-space for certain languages.

Because in some cases, the largest value only needs 2 characters, while in the Off state, space is needed for 3 characters.


For more information please see the PR linked above.
