java - 将字符串转换为 RTF 格式

Question

我想用我的程序生成 RTF 文档。我使用 RTFEditor，它以 rtf 格式提供编辑后的文本，但我也有 TextFields，我应该将 TextFields 中的字符串放入 RTF 文档中。我尝试编辑 rtf 文档文本，但我认为 ANSI 和 UTF-8 遇到了这个恼人的编码问题。如果我的 TextFields 得到带有“äöüß”的字符串......依此类推，我得到像“ö”这样的编码内容我的目标是获得一个美观的 RTF 文档，而没有编码问题。

处理此问题的最佳方法是什么？

这是我的类，它输出 rtf 文档:注意:请重点关注此代码中的重要内容。我希望我的代码中的德语术语不会让您感到困惑:)。

使用ISO-8859-1编码。此编码格式也将支持该字符。
