Does anyone have a quick solution.
I have a requirement to ensure fields are not stored with non printing whitespace characters.
So not “empty” but someone puts only spaces in the field.
This should be validator territory but it seems you cannot trigger a fragment validator if the field has spaces in it. Put in some alphas and all is good.
Frustrated 
I’m fairly sure I can come up with a solution “after” the field data is stored but id like to have prevented the data being entered in the first place.
mandatoryness is not the answer either - even if the field is mandatory blank spaces are a valid response technically.
That sounds like a bug so I’d raise a support ticket. The validator should fire on any value (apart from actually empty).
Will do Bob.
Was certainly a bit of surprise to me Thought I would check first to see if it was something id missed.
