国际化（2）
1. resource_en_US.properties
username=xiongfeiEnglish
2. resource_zh_CN.properties
username=\u718A\u975E\u4E2D\u6587 (熊非中文)
JDK中提供了一个native2ascii工具程序，可以将某种本地字符集编码的字符转换成Unicode转义序列的形式
Dos下进入a.properties文件所在目录，运行下面命令将在当前目录下生成一个名为b.properties的文件
native2ascii -encoding gb2312 源文件 目标文件
native2ascii -encoding gb2312 a.properties b.properties
3. resource.properties
username=\u96C4\u98DE\u9ED8\u8BA4 (雄飞默认)
