native2ascii.exe详细使用方法

native2ascii是sun java sdk提供的一个转码工具, 用来将别的文本类文件(比如 *.txt, *.ini, *.properties, *.java 等等)编码转为Unicode编码。

1. 如何获取 native2ascii.exe?

安装了jdk后,假如你是在windows上安装,那么在jdk的安装目录下,会有一个bin目录, 该目录下就有我们所需要的native2ascii.exe 工具。

2. native2ascii.exe使用方法:

命令的语法格式:

native2ascii -[options] [inputfile [outputfile]]

说明:

-[options]:表示命令开关,有两个选项可供选择

-reverse:将Unicode编码转为本地或者指定编码,不指定编码情况下,将转为本地编码。

-encoding encoding_name:转换为指定编码,encoding_name为编码名称。

[inputfile [outputfile]]

inputfile:表示输入文件全名。

outputfile:输出文件名。如果缺少此参数,将输出到控制台。

举例: 把需要进行国际化的文件(如下图)拷贝到 C:Program FilesJavajdk1.6.0_31in 目录下, 应用native2ascii.exe工具进行转码。

通过cmd命令进入DOS命令窗口进行如下操作:

通过native2ascii命令转码成功后,如下图:

备注:native2ascii.exe是一个应用比较简单的转码工具,并且转码是可逆的。

试试如下命令:

native2ascii -reverse new.txt yan.txt

结果:

native2ascii -encoding gbk old.txt new.txt

结果:
