Encoding CharsetNames for Charset.forName(String)
提问by Jason Ching
I have a question about Charset.forName(String charsetName). Is there a list of charsetNames I can refer to? For example, for UTF-8, we use "utf8" for the charsetName. What about WINDOWS-1252, GB18030, etc.?
我有一个关于 Charset.forName(String charsetName) 的问题。是否有我可以参考的 charsetNames 列表？例如，对于 UTF-8，我们使用“utf8”作为字符集名称。WINDOWS-1252、GB18030等呢？

Charset Description US-ASCII Seven-bit ASCII, a.k.a. ISO646-US, a.k.a. the Basic Latin block of the Unicode character set ISO-8859-1 ISO Latin Alphabet No. 1, a.k.a. ISO-LATIN-1 UTF-8 Eight-bit UCS Transformation Format UTF-16BE Sixteen-bit UCS Transformation Format, big-endian byte order UTF-16LE Sixteen-bit UCS Transformation Format, little-endian byte order UTF-16 Sixteen-bit UCS Transformation Format, byte order identified by an optional byte-order mark

The charset names in Java are platform dependent, there are only 6 constants in the StandardCharsetsclass.
Java 中的字符集名称是平台相关的，StandardCharsets类中只有 6 个常量。
To view the all charsets you should look at IANA. Check Preferred MIME Name and aliases columns.
要查看所有字符集，您应该查看IANA。检查首选 MIME 名称和别名列。

To list all character set installed in your JVM, you might use the following code snippet (Java 8 SE or higher):
要列出 JVM 中安装的所有字符集，您可以使用以下代码片段（Java 8 SE 或更高版本）：
SortedMap<String, Charset> map = Charset.availableCharsets();
map.keySet().stream().forEach(System.out::println);
On my system, this lists around 170 character sets.
在我的系统上，这列出了大约 170 个字符集。

The java Charset library is requiredto accept just a few basic encodings: ASCII, Latin-1 (ISO-8859-1), and a handful of UTF variants that you can see listed in this answer. That's a pretty useless list for any practical purposes, unless your scope is limited to Latin-1. In reality, Java classes can handle a large number of encodings that you can read about in the Supported Encodingspage. Quoting from it:
java Charset 库只需要接受一些基本编码：ASCII、Latin-1 (ISO-8859-1) 和一些您可以在此答案中看到的 UTF 变体。对于任何实际目的来说，这是一个非常无用的列表，除非您的范围仅限于 Latin-1。实际上，Java 类可以处理大量编码，您可以在Supported Encodings页面中了解这些编码。引用它：
The
java.io.InputStreamReader,java.io.OutputStreamWriter,java.lang.Stringclasses, and classes in thejava.nio.charsetpackage can convert between Unicode and a number of other character encodings. The supported encodings vary between different implementations of Java SE 8. The class description forjava.nio.charset.Charsetlists the encodings that any implementation of Java SE 8 is required to support.JDK 8 for all platforms (Solaris, Linux, and Microsoft Windows) and JRE 8 for Solaris and Linux support all encodings shown on this page.JRE 8 for Microsoft Windows may be installed as a complete international version or as a European languages version.

The rest of the pageconsists of an extensive table of encoding names and synonyms, which is what the OP was after all those years ago...
