java native2ascii的用法介绍
将非Unicode编码字符转化为Unicode编码的字符，即国际化。
语法：native2ascii [options] [inputfile [outputfile]]
描述：如果outputfile没有指定，标准输出将用于结果输出；如果inputfile没有指定，标准输入设备将用于输入。
参数
-reverse
使用该参数将Unicode编码字符转换为本地编码字符
-encoding encoding_name
用于指定转化时使用的字符编码。默认编码从系统属性file.encoding获取。后面的表格式字符编码，指定encoding_name使用表格第一栏。
-Joption
该参数一般无需使用，用于指定java虚拟机的启动参数。例如：-J-Xms48m设置虚拟机启动时分配内存为48M 。
Example1:
native2ascii test.txt test_unicode.txt
test.txt文件内容：native2ascii测试
test_unicode.txt文件内容：native2asciiu6d4bu8bd5
Example2:
native2ascii test_unicode.txt test_gbk.txt -reverse
test_gbk.txt内容：native2ascii测试
