UnderBar is a special case of Underscript:
{Underscript[12, 3], UnderBar[12]}Possible Issues (1)
Passing an operator as a string does not allow spanning behavior:
{Underscript[yyyy, "_"], Underscript[yyyy, "⇀"], Underscript[yyyy, "⥒"]}Use RawBoxes to pass the raw version of the operator, which allows it to span if possible:
{Underscript[yyyy, RawBoxes["_"]], Underscript[yyyy, RawBoxes["⇀"]], Underscript[yyyy, RawBoxes["⥒"]]}
