native2ascii解决java国际化问题

JDK中带了一个实用的程序native2ascii, 它可以根据指定的编码集在

本地字符和UNICODE字符之间进行转换. 本文给出了一些范例, 介绍了

怎样去使用这个程序.

1. 交互式:

直接敲入native2ascii, 程序光标会停在下一行,这时你可以直接敲入想

要转换的字符,例如输入"中国", 再按回车, 屏幕就会显示对应的

UNICODE编码 "u4e2du56fd"

按Ctrl +C 退出程序

2. 完整模式

1) Native char -> Unicode char

native2ascii -encodingXXX input_file output_file

先说说encoding这个参数: 在windows平台下就是代码页,例如

936表示简体中文,950表示繁体中文,949 表示韩文等等.

可以通过注册表键值查询到当前OS所支持的全部代码页:

HKEY_CLASSES_ROOT/MIME/Database/Codepage

example:

native2ascii -encoding MS936

c:/temp1.txt c:/temp2.txt

2) Unicode char -> Native char

native2ascii -reverse -encodingXXX input_file output_file

Example:

native2ascii -reverse -encoding MS936

c:/temp1.txt c:temp2.txt

注意: 如果指定了encoding, 要保证转换后的文件能正确显示,

需要安装对应的字体.

下面列举各个国家的编码代号

SYNOPSIS

native2ascii [options] [inputfile [outputfile]]

[/code]

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.

-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 a string taken from the first column of the table below.
