“?”s in “取る” are just numbers of a counter. So I think we can just use a custom css style to display those “?”s without adding extra SVGs.

.body, .level0 {
	counter-reset:section;
}
bc:before {
	font-family: "Hiragino Kaku Gothic ProN";
	counter-increment:section;
	content:counter(section);
	display: inline-block;
	line-height:1.3em;
	width: 16px;
	height: 16px;
	border-radius: 50%;
	font-size: 13px;
	font-weight: bold;
	color: #FAFAFA;
	text-align: center;
	background: #000000;
	position: relative;
	margin: 0 2px 0px 1px;
}
bc {font-size:0;}
