Oh yes look at that mess to circumvent the problem yes great job mate.
Technically you're right it's a line break not a carriage return that I already stated, So reading for the win 
now if you want to impress me get it to allow : and /
This is your thread, you reported the problem (and not the first person to do so only the most recent), I have no idea why you're wanting to pick a fight with me but all you're doing is working against your own interest here.
when we both know it's broken.. But I can get as dirty as you like.
P.S diplomacy pages have no such issue not sure why they don't just copy the validation from that to this or even use separate checks, but what ever I don't work here.
