无法在Android WebView中显示某些UTF-8字符

Question

I know this problem has been documented elsewhere but the solutions don't seem to work for me. 我知道这个问题已在其他地方记录，但解决方案似乎对我不起作用。 Other similar questions: 其他类似问题：

Android WebView UTF-8 not showing Android WebView UTF-8不显示

I'm essentially trying to show the minus/plus character (∓) in an android webview. 我实质上是想在Android Webview中显示减号/加号（∓）。 I tested several other characters 'around' the minus plus character in the UTF-8 table but some of them didn't work either 我在UTF-8表中测试了负号附近的其他几个字符，但其中一些也不起作用

Here is the java im using: 这是java im使用：

final WebView w = (WebView) findViewById(R.id.webview1);
w.getSettings().setJavaScriptEnabled(true);
w.getSettings().setDefaultTextEncodingName("utf-8");        

InputStream is;
try {
    is = getAssets().open("test5.html");

    int size = is.available();

    byte[] buffer = new byte[size];
    is.read(buffer);
    is.close();

    String str = new String(buffer);

    w.loadData(str, "text/html; charset=utf-8", "utf-8");

Here is the html test5.html 这是html test5.html

<html>
<head>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
</head>
<body>
    char: ∓ <br/>
    char: ∔ <br/>
    char: ∕ <br/>
    char: ∖ <br/>
    char: ∗ <br/>
    char: ∘ <br/>
</body>

The only characters that show up are the "∕" and "∗". 出现的唯一字符是“ ∕”和“ *”。 I've also tried 我也尝试过

w.loadDataWithBaseURL("file:///doesnotmatter", str, "text/html", "utf-8", "");

with no success. 没有成功。 I'm not too familiar with the input stream thing so I don't know if there's something wrong there. 我对输入流内容不太熟悉，所以我不知道那里是否有问题。 Please help, its taken me awhile =\\ 请帮助，它花了我一段时间= \\

Answer 1

调用loadData（）时 ，将编码以大写形式“ UTF-8”传递，因为它区分大小写，并且是文档中的标准表示形式。

Answer 2

use html codes for that characters in your html file: 在html文件中对该字符使用html代码：

<html>
<head>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
</head>
<body>
   char: &#8723;<br/>
   char: &#8724;<br/>
   char: &#8725;<br/>
   char: &#8726;<br/>
   char: &#8727;<br/>
   char: &#8728;<br/>
</body>
