The difficulty is that it isn't *possible* to give a single correct answer for the width of SHY, it varies and can only be identified when other information about the terminal is taken into account (how the terminal behaves and whether the word currently printed is being wrapped), which is out of scope for wcwidth(3). So no surprise different people come up with a different way to handle it. > If you want to show a hyphen in your text, use a hyphen.
