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
