Question

我想用我的程序生成一个RTF文档。我使用RTFEditor给出了rtfformat中的编辑文本，但我也有TextFields，我应该将TextFields中的Strings带入RTF Documeent。我试图编辑rtf文档文本，但我认为这有恼人的ANSI和UTF-8编码问题。如果我的TextFields获得了带有“äöüß”的字符串...依此类推，我会得到像“¶”这样的编码内容我的目标是获得一个没有编码问题的好看的RTF文档。

处理此问题的最佳方法是什么？

这是我输出rtf文档的类：注意：请关注此代码中的重要事项。我希望我的代码中的德语术语不会让你感到困惑:)。

    {
        //I want to insert my HeaderString into a specific position so i have to split etc...
        String content = new String();
        content = protokoll.getInhalt();

Answer 1

使用ISO-8859-1编码。这种编码格式也支持这些字符。

Answer 2

我讨厌角色编码......我相信以下博客可能会帮助你here

我会在这里发布代码，以防该网站将来出现问题，但请注意，我没有写这个，也不是我采取信用。

// Create a hashtable to hold the characters to convert
Hashtable<String, String> replace = new Hashtable<String, String>();

// The String to convert
String str = "The Māori Macron";

// Values we'll use in the loop
int value;
String bit;
for (int i = 0; i < str.length(); i++) {
    // Get the character value
    bit = str.substring(i, i + 1);
    value = str.codePointAt(i);

    // If the character value is above the
    // 7-bit range of RTF ASCII
    if (value > 127) {
        replace.put(bit, "\\\\u" + value + "\\\\'  ");
    }
}

// Now replace all the characters we found
Enumeration e = parameters.keys();
String key, value;
while (e.hasMoreElements()) {
    // Get the key
    key = (String)e.nextElement();

    // Get the value
    value = (String)parameters.get(key);

    // Make the substitution
    str = str.replaceAll(key, value);
}

将字符串放入RTF格式
