While these can be helpful, I'm not sure how widespread the availability is so you would probably want to provide these glyphs anyway. (I could be wrong here. But I also don't know a good way to assess their availability.) It's also quite nice that you can just type in data with Sparks and get sparklines which isn't possible with the glyphs you mentioned.
