In general, it marks boundaries in panes of text where spacing and alignment matter. When sharing across platforms, expect this symbol to appear as fullwidth on systems that support it, and it should be readable by assistive tech because it is a separate character.

Display and fallback: if you see an empty box (tofu) or a placeholder rectangle, the active font might not include this codepoint.
