使用Java创建包含国家字符的tar存档 [英] Creating tar archive with national characters in Java

问题描述

您是否知道Java中的某些库/方式可以在适当的Windows国家代码页（例如cp1250）中生成带有文件名的tar存档。

Do you know some library/way in Java to generate tar archive with file names in proper windows national codepage ( for example cp1250 ).

我试过 Java tar ，示例代码：

final TarEntry entry = new TarEntry( files[i] );
String filename = files[i].getPath().replaceAll( baseDir, "" );
entry.setName( new String( filename.getBytes(), "Cp1250" ) );
out.putNextEntry( entry );
...

它不起作用。在Windows中提取tar时，国家字符被破坏了。
我也发现了一件奇怪的事情，在Linux下波兰国家字符只有在我使用ISO-8859-1时才能正确显示：

It doesn't work. National characters are broken where I extract tar in windows. I've also found a strange thing, under Linux Polish national characters are shown correctly only when I used ISO-8859-1:

entry.setName( new String( filename.getBytes(), "ISO-8859-1" ) );

尽管正确的波兰语代码页是ISO-8859-2，但这也不起作用。
我也试过Windows的Cp852，没效果。

Despite the fact that proper Polish codepage is ISO-8859-2, which doesn't work too. I've also tried Cp852 for windows, no effect.

我知道tar格式的限制，但更改它不是一种选择。

I know the limitations of tar format, but changing it is not an option.

感谢您的建议，

推荐答案

正式地，TAR不支持标头中的非ASCII。但是，我能够在Linux上使用UTF-8编码的文件名。

Officially, TAR doesn't support non-ASCII in headers. However, I was able to use UTF-8 encoded filenames on Linux.

你应该试试这个，

String filename = files[i].getName();
byte[] bytes = filename.getBytes("Cp1250")
entry.setName(new String(bytes, "ISO-8859-1"));
out.putNextEntry( entry );

这至少保留了TAR标题中Cp1250中的字节。

This at least preserves the bytes in Cp1250 in TAR headers.
