在处理Android上的XML文件后，奇怪的字符

我正在从一个XML文件加载数据的Andorid的应用程序了。问题是，XML文件是不正确处理，我不能序列化，因为这一点。我认为这个问题是涉及到文件的编码。

I am making an andorid applicaiton which loads data from a xml file. The problem is that the xml file is not processed correctly and I am not able to serialize it, because of that. I think the problem is related to the encoding of the file.

如何我做了xml文件？从Eclipse的我已经点击新建 - >文件 - >并创建了一个空白的XML，然后我和所需信息填写它

How I made the xml file? From Eclipse I have clicked on New-> File -> and created a blank xml, then I've filled it with the needed information.

下面是XML的外观在编辑器：

Here is how the xml looks in the editor:

<?xml version="1.0" encoding="UTF-8"?>
<data>
<categories>
    <category value="Inbox"/>
    <category value="Private"/>
    <category value="Work"/>
    <category value="Business"/>
</categories>

<todos>
    <todo>
        <id>1</id>
        <text>Explore the app!</text>
    </todo>

    <todo>
        <id>2</id>
        <text>Add more todos!</text>
       <date>2013-05-09 12:21:55 CET</date>
   </todo>
</todos>
</data>

我收到来自RES / XML的XML文件，然后我加载输入流中的文件。之后，我使用String构造的文件转换为字符串。

I am getting the xml file from res/xml and then I load the file in an Input Stream. After that I am converting the file to a String using the String constructor.

下面是java code：

Here is the java code:

    InputStream is = getResources().openRawResource(R.xml.startingdata);
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    int next = is.read();
    while (next > -1) {
        bos.write(next);
        next = is.read();
    }
    bos.flush();
    byte[] result = bos.toByteArray();
    xmldata = new String(result,"UTF-8");

这一步后，我展现新XMLDATA来敬酒，以检查它的外观。不过，我接收到的数据，再加上一些奇怪的字符的一部分。我做错了什么？先谢谢你！
我从我的测试设备连接的图像，为您展示怪异敬酒结果是：

after this step, I show the new xmldata to a Toast, to check how it looks. However I receive part of the data, plus some weird characters. What I am doing wrong? Thank you in advance! I am attaching an image from my testing device, in order to show you the weird toast result:
