1. Overview

1.概述

Eclipse is a very popular integrated development environment (IDE) used for various programming languages. It’s cross-platform, available for free, and primarily used for Java applications.

Eclipse 是一种非常流行的集成开发环境（IDE），用于各种编程语言。它跨平台、免费提供，主要用于 Java 应用程序。

It’s necessary to have UTF character encoding when working with Java-based applications, specifically when our application needs to handle various kinds of languages.

在使用基于 Java 的应用程序时，特别是当我们的应用程序需要处理各种语言时，有必要使用 UTF 字符编码。

In this tutorial, we’ll explore how to support UTF-8 encoding in Eclipse. Furthermore, we’ll learn the use and importance of UTF-8 encoding in an application.

在本教程中，我们将探讨如何在 Eclipse 中支持 UTF-8 编码。此外，我们还将了解 UTF-8 编码在应用程序中的用途和重要性。

2. Benefits of UTF-8 Encoding

2.UTF-8 编码的好处

UFT-8 is a versatile 8-bit character encoding that supports all characters and symbols from various languages and scripts.

UFT-8 是一种通用的8 位字符编码，支持各种语言和脚本的所有字符和符号。

Additionally, it’s widely supported by various programming languages, platforms, and engineering standards.

此外，它还受到各种编程语言、平台和工程标准的广泛支持。

Also, it has seamless compatibility with ASCII character encoding. This gives it an extra edge over other encodings.

此外，它还与ASCII字符编码无缝兼容。这使它比其他编码方式更具优势。

Furthermore, it permits developers to build very reliable and globally acceptable applications with the support of data exchange formats.

此外，它还允许开发人员在数据交换格式的支持下，构建非常可靠且可被全球接受的应用程序。

3. Global Configuration

3.全局配置

Enabling UTF-8 encoding in Eclipse is an essential and straightforward process for developers as it ensures the source code is properly encoded. It further enables applications to have a wide range of characters available.

在 Eclipse 中启用 UTF-8 编码对于开发人员来说是一个重要而简单的过程，因为它可以确保源代码得到正确编码。它还能使应用程序拥有更多可用字符。

To illustrate, let’s look at the steps to enable UTF-8 encoding:

为了说明这一点，让我们来看看启用 UTF-8 编码的步骤：

  • Open the Eclipse IDE
  • Click on the Eclipse in the top menu
  • Click on Settings
  • Click on General > Workspace
  • Check the box next to Default (UTF-8) under Text file encoding

The above-explained entire process is visible in the GUI below:

下面的图形用户界面显示了上述整个过程：

default UTF-8 encoding
By following the steps above, we can enable UTF-8 encoding in Eclipse.

默认 UTF-8 编码
按照上述步骤，我们就可以在 Eclipse 中启用 UTF-8 编码。

Eventually, it permits us to add support for various languages to our project. Furthermore, UTF-8 enables the internationalization and localization of various features and characters from different languages that can be handled consistently across the system.

最终，它允许我们在项目中添加对各种语言的支持。此外，UTF-8 还可以实现不同语言的各种功能和字符的国际化和本地化，并在整个系统中进行一致的处理。

4. Enable UTF-8 Encoding per File Type

4.为每个文件类型启用 UTF-8 编码

In Eclipse, we can also enable UTF-8 encoding per file type.

在 Eclipse 中，我们还可以为每种文件类型启用 UTF-8 编码。

To illustrate, let’s look at the steps to perform this:

为了说明这一点，让我们来看看执行的步骤：

  • Open the Eclipse IDE
  • Click on the Eclipse in the top menu
  • Click on Settings
  • Click on General > Content Types
  • Pick a File Type (Java Class File)
  • Add UTF-8 to the “Default encoding”

Let’s look at the whole process of enabling UTF-8 encoding:

让我们来看看启用 UTF-8 编码的整个过程：

UTF-8 encoding perFileType

This way, we can enable UTF-8 encoding per file type.

这样，我们就可以为每种文件类型启用 UTF-8 编码。

5. Conclusion

5.结论

In this article, we explored various ways to enable UTF-8 encoding.

在本文中，我们探讨了启用 UTF-8 编码的各种方法。

First, we enabled UTF-8 encoding for all projects in Eclipse. After that, we looked at enabling UTF-8 encoding per file type.

首先，我们为 Eclipse 中的所有项目启用了 UTF-8 编码。之后，我们查看了每种文件类型启用 UTF-8 编码的情况。
