# 输入特殊字符

You can enter and view thousands of characters from most of the world’s writing systems, even those not found on your keyboard. This page lists some different ways you can enter special characters.

# 输入字符的方法

# Characters

Another useful application shipped with GNOME is Characters. It lets you find and insert unusual characters by browsing character categories or searching for keywords.

You can launch Characters from the Activities overview. For more information on Characters, see the Characters Manual.

# Compose 键

Compose 键是一种特殊按键，可以按多个键序列得到一个特殊字符，例如，要输入重音符号 é，您可以按住 compose 然后再按 ' 和 e 键。

Keyboards don’t have specific compose keys. Instead, you can define one of the existing keys on your keyboard as a compose key.

You need to have Tweaks installed on your computer to change this setting.

Install Tweaks

## 定义一个 compose 键

Open the Activities overview and start typing Tweaks.

Click Tweaks to open the application.

Click the Keyboard & Mouse tab.

Click Disabled next to the Compose Key setting.

Turn the switch on in the dialog and pick the keyboard shortcut you want to use.

Tick the checkbox of the key that you want to set as the Compose key.

Close the dialog.

Close the Tweaks window.

您可以用 compose 键输入多种字符，例如：

按住 compose 键，然后按 ' 键，可以输入重音符号，像 é。

按住 compose 键，然后按 ` (反引号)键，可以输入抑音符号，像 è。

按住 compose 键，然后按 " ，可以输入变音符号，像 ë。

按住 compose 键，然后按 - ，可以输入长音符号，像 ē。

更多的 compose 键序列，请参阅 Wikipedia 上的 compose 键.

# 代码点

您可以用键盘输入任何一个 Unicode 字符，只要输入这个字符的代码点数值。每个字符由一个四字符码来标识。要查找一个字符的四字符码，在字符映射表程序中找到这个字符，然后在状态栏中或在字符细节中找到，代码点是在U+ 后面的四字符码。

To enter a character by its code point, hold down Ctrl and Shift, type U followed by the four-character code point, then release Ctrl and Shift. If you often use characters that you can’t easily access with other methods, you might find it useful to memorize the code point for those characters so you can enter them quickly.

# 键盘布局

您可以让键盘变成其他语言布局，而不是原来键盘上标识的字母了，您甚至可以使用顶部面板上的一个图标，轻松地在不同语言之间切换，详细介绍请参阅 。

# 输入法

An Input Method expands the previous methods by allowing to enter characters not only with keyboard but also any input devices. For instance you could enter characters with a mouse using a gesture method, or enter Japanese characters using a Latin keyboard.

要选择一个输入法，在输入控件上点击右键，在输入法菜单中选择一种需要的输入法。尚没有完全成为事实标准的统一的输入法，请参考输入法的文档查看如何使用。
