Upwards triangle-headed arrow

Same meaning, different character and a bolder head.

⭡ belongs to a set of four arrows (⭠ ⭢ ⭡ ⭣) with neat matching triangular heads, rooted in the symbols printed on keyboard keys. The common up arrow ↑ is a separate character. They look alike, but find-and-replace in a document treats them as different, so pick one and use it consistently.

Because ⭡ is a text symbol, its look comes from the font. Font support varies, and a font that lacks it may show an empty box or another placeholder. If your reader might see a box, ↑ is the safer choice.
