    function 

    Public Function DisplayWidth(text: String): Int

    The columns text takes in a terminal, each grapheme cluster as many as its widest character, so "e" with its accent is 1, and an emoji made of several is 2. A flag is 2, and so is a character that U+FE0F asks to be drawn as emoji, like "\u{2764}\u{FE0F}", though it's 1 alone.
