font awesome不显示

Question

我有下面的带Boostrap的HTML代码。我正在尝试用Font Awesome图标4.7.0填充一个列表。但它只显示第一个图标，其他图标不显示它们。

​

<link href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="stylesheet"/>
<div class="input-group" style="margin-bottom:9%">
  <div class="input-group-append" style="width: 40%;">
    <select class="form-control fa" name="selectableList">
      <option class="fa fa-search" value="0">&#xf002;</option>
      <option class="fa fa-equals" value="1">&#xf52c;</option>
      <option class="fa fa-not-equal" value="2">&#xf53e;</option>
      <option class="fa fa-spell-check" value="3">&#xf891;</option>
      <option class="fa fa-remove-format" value="4">&#xf87d;</option>
    </select>
  </div>
  <input class="form-control" type="text" name="textInput" />
</div>

试试Font Awesome 5

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.11.2/css/all.min.css" integrity="sha256-+N4/V/SbAFiW1MPBCXnfnP9QSN3+Keu+NlB+0ev/YKQ=" crossorigin="anonymous" />
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="stylesheet"/>

<div class="input-group" style="margin-bottom:9%">
  <div class="input-group-append" style="width: 40%;">
    <select class="form-control fa" name="selectableList">
      <option class="fa fa-search" value="0">&#xf002;</option>
      <option class="fa fa-equals" value="1">&#xf52c;</option>
      <option class="fa fa-not-equal" value="2">&#xf53e;</option>
      <option class="fa fa-spell-check" value="3">&#xf891;</option>

感谢所有人的回答，确实是User863提出的解决方案。

如果你不能更新字体令人敬畏的版本，有一个替代方案，使用unicode symbols。

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="stylesheet" />
<div class="input-group" style="margin-bottom:9%">
  <div class="input-group-append" style="width: 35%;">
    <select class="form-control fa" name="searchTypeCampaing" style="font-size: 18px;font-family: Arial, FontAwesome;font-weight: bold;">
      <option class="fa fa-search" value="0">&#xf002</option>
