To measure the columns needed to print a string, you'll need the number of graphemes. (d|)?string.length gives you the number of code units.
Even that's not really true. In the end it's up to the font and layout engine to decide how much space anything takes up. Unicode doesn't play nicely with the idea of text as a grid of rows and fixed-width columns of characters, although quite a lot can (and is, see urxvt for example) be shoe-horned in.
