i是无效的SVG。您需要包括显示图标的实际字符。如果您查看fontawesome的样式表，您将看到…
.icon-group:before { content: "f0c0"; }.icon-link:before { content: "f0c1"; }.icon-cloud:before { content: "f0c2"; }.icon-beaker:before { content: "f0c3"; }.icon-cut:before { content: "f0c4"; }.icon-copy:before { content: "f0c5"; }.icon-paper-clip:before{ content: "f0c6"; }.icon-save:before { content: "f0c7"; }.icon-sign-blank:before{ content: "f0c8"; }.icon-reorder:before { content: "f0c9"; }.icon-list-ul:before { content: "f0ca"; }.icon-list-ol:before { content: "f0cb"; }.icon-strikethrough:before { content: "f0cc"; }.icon-underline:before { content: "f0cd"; }.icon-table:before { content: "f0ce"; }但是那些是为CSS编码的unipre字符。在SVG中，您需要将example的语法更改
f040为：
<g><text x="0" y="0"></text></g>
然后在样式表中添加：
svg text { font-family: FontAwesome;}
