About the fullwidth low line symbol

This character is read as a low line or underscore. It is the fullwidth variant of the standard underscore, occupying the same horizontal space as a fullwidth CJK character. It is used in East Asian typography when a continuous, monospaced visual underlining effect is needed in text, such as in forms, tables, or plain-text formatting. It also appears in some contexts as a placeholder or filler character in monospaced environments.
