java 国际化工具 native2ascii工具使用

native2ascii 是jdk 提供的标准的转化字符的工具

它的功能是把本地代码即（本地中文，日文，等等文本文件） 转化为unicode编码的文本文件（这样说可能不严谨，不过却容易理解）

关于它的用法，其实标准的jdk文档里都是有的，我用的jdk5.0的.chm格式的文档。我把它贴出来

native2ascii - Native-to-ASCII Converter

Converts a file with native-encoded characters (characters which are non-Latin 1 and non-Unicode) to one with Unicode-encoded characters.

SYNOPSIS

native2ascii [options] [inputfile [outputfile]]

DESCRIPTION

The Java compiler and other Java tools can only process files which contain Latin-1 and/or Unicode-encoded (/udddd notation) characters. native2ascii converts files which contain other character encodings into files containing Latin-1 and/or Unicode-encoded charaters.

If outputfile is omitted, standard output is used for output. If, in addition, inputfile is omitted, standard input is used for input.

OPTIONS

-reverse

Perform the reverse operation: convert a file with Latin-1 and/or Unicode encoded characters to one with native-encoded characters.
这个参数把unicode字符的文本文件内容转化成容易识别的本地文本文件

-encoding encoding_name

Specify the encoding name which is used by the conversion procedure. The default encoding is taken from System property file.encoding. The encoding_name string must be taken from the first column of the table of supported encodings in the Supported Encodings document.

 

-J option

Pass option to the Java virtual machine, where option is one of the options described on the reference page for the java application launcher. For example, -J-Xms48m sets the startup memory to 48 megabytes.

注意命令参数中 -reverse 和 -encoding是可以一起出现的。
