Punctuation triggering 70-character max SMS
Has anyone noticed that when sending an SMS from iPhone (did it on my 64gb 6S+ and is currently on my 64gb 8+) to an Android phone, the punctuation marks ' and " will trigger the character count to drop from 160 max to 70? Obviously it does it if you use an emoji, but I wonder if there's some bug in iOS that is seeing these punctuation marks as objects instead of characters or something. I can't remember if it has been since before the iOS 11 update that this has been going on or not. Also my carrier is Sprint.
iPhone 8 Plus, iOS 11
