Java 1.5，Linux
我的屏幕包含不同的textareas和textfields。 我确实有应用程序框架，但没有访问框架内的组件，因为我只获得了一个接口的实现。
当我尝试添加德语变音符时，我在文本组件中看到一个矩形，因为该字符不受支持。 我需要设置哪种字体或哪种系统属性来支持linux下的“变音符号”。 在Windows上，字符显示正确。

这听起来像是字符编码问题或字体问题......就像在Linux环境中使用“windows”编码一样。您应该检查以下内容：
如果你告诉你这样做会发生什么，我们可能会更好地了解出了什么问题。 ：）
<强>更新 我想让你检查这个的原因是我知道所谓的“windows编码”会在其他操作系统中产生问题。你说你可以在控制台上写变音符号而不是在vi中，你会得到什么，方块？
用户不想查看ini文件，如果你在Linux中手动创建了ini文件，我认为你可以编写变音符号。您应该找出这些文件和TCP连接使用的字符编码。它应该是UTF-8，“Western”或“Windows”或“Latin-1”等可能会导致问题。
如果一切都是UTF-8，除了应用程序之外的任何地方都可读，我会开始怀疑缺少字体问题。

我的猜测是桌面（KDE或Gnome）被配置为使用不包含变音符号的字体（有点奇怪，今天，但它发生了）。 Java通常会尝试使用系统字体作为计算“Dialog”字体的基础（即使未安装它也始终可用;“Dialog”是Java用来表示“Default sans-serif font”的虚拟字体名称）。

方框是unicode符号，用于当字体不包含该字符时无法显示该字符。
您需要将文本框切换为包含德语字符的字体，或者找到另一种方法来替换该字符（在Java中可能无法实现）。

“vi”没有显示äöü
字符串是通过tcp连接发送的，或者是从在os
上创建的ini文件中读取的不会发生，不重要
我现在不能测试

在控制台上我可以提示äöü
echo $TERM --> vt100
命令：
'find / | grep font'

答案 5 :(得分：0)
我写了一个swing测试，我选择了每个可用于Java的字体。
Font[] fonts = GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts();
这些字体我可以将变音符写入jpanel，当我将jpanel的字体设置为给定的字体时。它们全部正确显示。
我在一个文件中读到了我认为在另一台PC上创建的文件。我必须要求确定此文件的来源。 我从tcp连接获得的字符串可以正确显示。 我从文件中读取的字符串是我无法显示的字符串。 谢谢你的回答。我将检查文件格式是否错误。
