类名称：ZipEncoding

ZipEncoding介绍

[英]An interface for encoders that do a pretty encoding of ZIP filenames.

There are mostly two implementations, one that uses java.nio java.nio.charset.Charset and one implementation, which copes with simple 8 bit charsets, because java-1.4 did not support Cp437 in java.nio.

The main reason for defining an own encoding layer comes from the problems with java.lang.String#getBytes(String), which encodes unknown characters as ASCII quotation marks ('?'). Quotation marks are per definition an invalid filename on some operating systems like Windows, which leads to ignored ZIP entries.

All implementations should implement this interface in a reentrant way.
[中]一个用于编码器的接口，可以对ZIP文件名进行漂亮的编码。
主要有两种实现，一种使用java。nio java。尼奥。查塞特。字符集和一个实现，它处理简单的8位字符集，因为java-1.4不支持java中的Cp437。尼奥。
定义自己的编码层的主要原因来自java的问题。lang.String#getBytes（String），它将未知字符编码为ASCII引号（“？”）。根据定义，引号在某些操作系统（如Windows）上是无效的文件名，这会导致忽略ZIP条目。
所有的实现都应该以可重入的方式实现这个接口。
