Counting graphemes may be over-used, but needing to know their boundaries is important (and leads naturally to counting). For example, when you hit "delete" in a text editor, you'll probably want it to delete whole graphemes (and similarly for text selection); if you're doing text truncation, you may measure it by pixels, but you'll want to chop off the excess bytes at a grapheme boundary.
