可编译为 UNICODE 和 ANSI 版本的遍历目录树程序_0.1
路径暂时是写死的
编译两个版本的程序：
g++ treeT.cpp -municode -D_UNICODE -o treeT_UNI
g++ treeT.cpp -o treeT_ASC
为了观察ANSI版在遍历文件夹如果遇到Unicode字符会发生什么情况而写来作对比的
他们都可以接收终端传送的中文字符
ANSI版：
opendir/readdir 遍历目录遇到 UNICODE字符的时候会出问题
UNICODE版：
输出到stdout的时候，值>128 的UNICODE字符丢失
改为 WriteConsoleW 函数可以解决这个问题
