文本字段“元音变音”未在 linux 上显示

Question

Java 1.5，Linux

我确实有一个包含不同文本区域和文本字段的屏幕。 我确实可以访问应用程序框架，但不能访问框架内的组件，因为我只获得了接口的实现。

当我尝试添加德语变音符号时，我在文本组件中看到一个矩形，因为不支持该字符。 我必须设置哪种字体或哪个系统属性以支持 linux 下的“元音变音”。 在 Windows 上，字符显示正确。

Answer 1

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：

• 你能在你的Linux发行版的普通文本编辑器中写这些字符吗？
• 这些字符是来自您的 java 应用程序中的输入文件还是来自源代码，如果是，您使用什么操作系统编写源代码？
• 如果它们来自源文件或资源文件，您是否检查过这些字符在 Linux 的源文件中是否真正可读？
• 如果您在 vim 中打开源文件，它使用什么编码？ （通常在您打开文件后屏幕下方会显示）

如果您告诉执行此操作时会发生什么，我们可能会更好地了解问题所在。 :)

更新： 我希望您检查这一点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，但不能在 vi 中，你会得到什么，方块？

用户不应该查看 ini 文件并不重要，如果您在 Linux 中手动创建 ini 文件，我想您那时可以编写变音符号。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，除了在您的应用程序中之外的任何地方都可读，我会开始怀疑缺少字体问题。

Answer 2

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（今天有点奇怪，但确实发生了）。 Java 通常尝试使用系统字体作为计算“Dialog”字体的基础（即使未安装也始终可用；“Dialog”是 Java 用来表示“Default sans-serif font”的虚拟字体名称)。

• 使用 xlsfonts 检查安装了哪些字体
• 检查是否可以在控制台输入变音符号
• 尝试其他 Java 应用程序
• 检查 $JAVA_HOME/jre/lib/fonts (IIRC)。我想你可以在那里找到字体映射。

Answer 3

方框是 unicode 符号，用于当相关字符因字体不包含而无法显示时。

您需要将文本框切换为包含德语字符的字体，或者找到其他方法来替换该字符（这在 Java 中可能无法实现）。

Answer 4

• 你能在你的 Linux 发行版的普通文本编辑器中编写这些字符吗？

“vi”不显示äöü

• 这些字符是来自您的 java 应用程序中的输入文件还是来自源代码，如果是，您使用什么操作系统编写源代码？

字符串由 tcp 连接发送或从操作系统上创建的 ini 文件中读取

• 如果它们来自源文件或资源文件，您是否检查过这些字符在 Linux 的源文件中是否真正可读？

不会发生，不重要

• 如果您在 vim 中打开源文件，它使用什么编码？ （通常在您打开文件后屏幕下方会显示）

我现在不能测试吗

Answer 5

• 检查是否可以在控制台输入变音符号

在控制台上我可以给小费 äöü

echo $TERM --> vt100

• 使用 xlsfonts 检查安装了哪些字体

命令：

'find / | grep font'

结果：

Answer 6

我编写了一个摇摆测试，在其中我选择了我可以在 Java 中使用的所有可用字体。

Font[] fonts = GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts();

当我将 jpanel 的字体设置为给定的字体时，我可以使用这些字体将变音符号写入 jpanel。它们都显示正确。

我读入了一个我认为是在另一台电脑上创建的文件。我必须询问以确定该文件的来源。 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。我会检查文件是否格式错误。
