How people use this symbol

The √ square root is commonly copied for profiles, captions, UI labels, notes, and short-form text where people want more control than emoji styling usually gives them.

It fits especially well in plain text layouts because the character is lightweight, easy to paste, and usually easier to align with surrounding words than a colorful emoji glyph.
