但这些是为 CSS 编码的 unicode 字符。在 SVG 中，您需要将示例
\f040<g><text x="0" y="0"></text></g>
然后在样式表中添加：
svg text {
font-family: FontAwesome;
}
根据 Niek 的评论，如果您使用免费版本的 Font Awesome 5+，则必须使用以下字体系列声明：
svg text {
font-family: 'Font Awesome 5 Free';
}

JS
var svg = d3.select("body")
.append("svg")
.attr("width", 250)
.attr("height", 250);
svg.append("text")
.attr("x",0)
.attr("y",70)
.attr("font-family","FontAwesome")
.attr('font-size', function(d) { return '70px';} )
.text(function(d) { return '\uf083'; });
下面的代码非常适合我。
svg.append('tspan')
.attr('class', 'fa')
.text('\uf05a')
