See #41 (comment)

Suggestion is to prevent entering the "0" setting. If a character type requirement is "enabled" then the number must be at least 1.

@phil-davis correct, I have set the min-value of html input to 1.
But this is indeed just working if you use the controls, you could easily enter a 0 char.
To come all over this, we need a backend validator, and this is too much for this particular issue.
