场景:
1.本以为vs设置了源文件的UTF8编码,代码中出现的中文字符串就一定是utf8编码了，可惜不是，如果源码中出现了中文字符串，会在内存中转码为ANSI编码。
Unicode(UTF8带签名) 代码页(65001)，从菜单->文件->高级保存选项 设置.
例子:
char path[] = "resources\\中文\\";
for(int i = 0; i < strlen(path); ++i)
{
printf("0x%x,",(unsigned char)path[i]);
}
查看UTF8文件十六进制 0x72,0x65,0x73,0x6F,0x75,0x72,0x63,0x65,0x73,0x5C,0x5C,0xE4,0xB8,0xAD,0xE6,0x96,0x87,0x5C,0x5C 打印出来的内存: 0x72,0x65,0x73,0x6f,0x75,0x72,0x63,0x65,0x73,0x5c,0xd6,0xd0,0xce,0xc4,0x5c 明显"中文”的文件编码是 0xE4,0xB8,0xAD,0xE6,0x96,0x87 而载入内存且变成了,这个编码是ANSI编码,也就是本地编码(GB2312). 0xd6,0xd0,0xce,0xc4 结论就是: vs源码上不要出现utf8的中文字符串，会被转码为ansi编码.
