I need to set different font to a label based on whether I'm displaying simple English string or characters from other languages that are not based on the latin characterset. So I just want to know whether if the entire string is all latin characters? How can I do that in Swift? I have read this question, but I don't think I can apply that answer because there is no way I can specify all the latin character including the mark and punctuation, one by one, to be excluded in the detection.
Please help. Thanks.
