When to use it
⇑ writes U+21D1 (Upwards Double Arrow), a symbol from the Unicode Arrows block, encoded since Unicode 1.1. Arrow shapes vary a lot between fonts; when an arrow is the only content of a link or button, give it a text label as well.
The name dates from HTML 4, so it works in every browser and in old email clients.
