native2ascii知识点详解

java程序显示中文是大家都遇到过的问题，尤其是JAD文件的中文问题，一般都用native2ascii工具转换，这里收藏了native2ascii工具的详细说明：

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.
 

-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.

不过WTK可以直接解决JAD的中文问题：
settings>MidLets>MidLet-1属性改成你想要显示的中文后重新生成JAD和JAR文件即可。
