Frequently asked questions

Why does my post count differently on each platform?

They count different things. X counts most characters as one but CJK as two and gives every link a fixed length; Instagram and LinkedIn count UTF-16 code units, so an emoji can cost two. The counter applies each platform's own rule rather than one number for all of them.
