Eclipse: I turned on hidden characters now I can't turn off
提问by Brett
Somehow I've turned on hidden characters in Eclipse. It's not the "whitespace" characters in the general editor preferences. When turned on, it adds another layer of hidden characters over the existing ones.
不知何故，我在 Eclipse 中打开了隐藏字符。它不是一般编辑器首选项中的“空白”字符。打开后，它会在现有字符上添加另一层隐藏字符。
Then I have things like

Does anyone know what these are and how to remove them?

It is under Preferences > General > Editors > Text Editors. There is a checkbox labeled "Show whitespace characters". If you uncheck this the editor switches back to normal.
它位于首选项 > 常规 > 编辑器 > 文本编辑器下。有一个标记为“显示空白字符”的复选框。如果取消选中此项，编辑器将恢复正常。
If you click on the "whitespace characters" link in this line you will get a popup window, in which you can define which characters eclipse is supposed to consider as whitespace characters.
如果单击此行中的“空白字符”链接，您将看到一个弹出窗口，您可以在其中定义 eclipse 应该将哪些字符视为空白字符。
In this popup window you also get the option to define the transparency in which each whitespace character is displayed in the editor, which you can use to (indirectly) change their foreground colour. I'm just mentioning it here, because it took me about half an hour to find this setting! ;-)
在此弹出窗口中，您还可以选择定义每个空白字符在编辑器中显示的透明度，您可以使用它来（间接）更改其前景色。我只是在这里提到它，因为我花了大约半个小时才找到这个设置！;-)

It is actually in two places...
其实有两个地方...
Sandkastenliga points out the obvious one, but you can also show white space with a shortcut key combination. The key combination is separate from the text editor preferences and will superimpose additional characters when active (it uses \r and \n for carriage return an line feed respectively instead of the symbols used by the text editor preference.)
Sandkastenliga 指出了一个显而易见的问题，但您也可以使用快捷键组合来显示空白。组合键与文本编辑器首选项分开，并在活动时叠加其他字符（它使用 \r 和 \n 分别回车换行，而不是文本编辑器首选项使用的符号。）
Go to preferences > general > keys and look for the binding for the 'Show Whitespace' command.
转到首选项> 常规> 键并查找“显示空白”命令的绑定。
I have the text editor preference turned on, so I removed the binding for this command altogether (it was set to Ctrl+. in my profile) to prevent accidental activation as it doesn't affect the other preference.
我打开了文本编辑器首选项，因此我完全删除了此命令的绑定（在我的配置文件中设置为 Ctrl+.）以防止意外激活，因为它不会影响其他首选项。

You can add "Show Whitespace Characters" button in toolbar by customizing your perspective. It also contains buttons to toggle word wrap, and toggle selection mode.
您可以通过自定义视角在工具栏中添加“显示空白字符”按钮。它还包含用于切换自动换行和切换选择模式的按钮。
Go to Window > Perspective > Customize Perspective > Action Set Availability, then select "Editor Presentation" action set:

This works in Eclipse Neon.
