该问题存在于CSS中。我发现下面的样式块嵌入到基本样式表中。“字体功能设置”，使您可以控制OpenType字体中的高级排版功能“liga”指连字，dlig指任意连字。这两者都包含在OpenType字体集中。

p {
        -webkit-font-feature-settings: "liga", "dlig";
        -moz-font-feature-settings: "liga=1, dlig=1";
        -ms-font-feature-settings: "liga", "dlig";
        -o-font-feature-settings: "liga", "dlig";
        font-feature-settings: "liga", "dlig";
    }
