This is a great hack, but it makes bad sparklines. It’s probably about as good as you can get with unicode, so props to Jon.
Sparklines have a few important properties which these do not exhibit. They’re typically higher resolution, with more data per inch. Also the slopes from point to point, and the whitespace under the typical graph/sparkline, help readability.
