What ⃯ means
Append ⃯ after one base; use a math command for formulas.
As a bottom accent, ⃯ attaches to the preceding character, marking one variable rather than spanning a whole expression. In LaTeX math, \underrightarrow{...} draws an arrow under a full expression.
A 2004 Unicode math proposal completed an existing set of arrow accents with this mark for use beneath variables or mathematical expressions. The date marks the encoding proposal, not the origin of under-arrow notation.
Why does ⃯ disappear or sit off-center?
Fonts and math engines control whether ⃯ appears and where it sits.
A 2023 typesetting report found ⃯ missing in Cambria but present in Latin Modern Math and STIX Two Math; bottom-accent placement also varied across fonts and engines.
A dotted-circle sample in a character chart is only a display aid: in actual text, ⃯ follows a base.
What does ⃯ mean when it arrives alone?
By itself, ⃯ is incomplete mathematical notation.
Its reading depends on the variable or expression it marks. If someone sends it alone, ask what base expression it belongs to before treating it as a message.
Technical and formal; it suits mathematical expressions, not casual standalone messages.
Alone, ⃯ is incomplete; ask what base it belongs to.

1Can ⃯ go under a whole equation?
No. It attaches to the single character before it; a math layout command such as \underrightarrow{...} spans an expression.
