以前写的一个小web应用终于可以在这个版本的windows上稳定运行了，有两点经验：

1）控制台输出是utf8编码，所以在Windows上是乱码。我使用了一个简单的处理办法，用C语言写了一个打印UTF8的的程序，也就10来行代码，然后利用管道符连接：

         MyApp.exe | printUtf8.exe
2）path包的路径分隔符使用的是 “/” , 进行文件处理时要注意。

[chai]

UTF8转本地编码比较实用，希望go以后能加这个功能。

你的printUtf8.exe放在哪呢？

[qq wu]

编码转换对于go是不是原生支持，倒也无关紧要，因为通过调用libiconv这些库很容易实现。Windows下现在似乎cgo还不能用，但也可以通过syscall调用。

在 windows 下实现这个 printUtf8 也超简单：

#include <windows.h>

#define BUFSIZE 256

char buf[BUFSIZE*2];

wchar_t wbuf[BUFSIZE];

int main(int argc, char **argv) {

char *p;

while ((p = fgets(buf, BUFSIZE, stdin))) {

MultiByteToWideChar(CP_UTF8, 0, p, -1, wbuf, BUFSIZE);

WideCharToMultiByte(CP_ACP, 0, wbuf, -1, buf, sizeof(buf), 0, 0);

fputs(buf, stdout);

}

return 0;

}

现在的程序哪有用控制台的了，知道怎么创建windows窗口么？

既然是Web应用，当然是 Web GUI了，控制台是用来调试的。

要做Windows窗口或者桌面应用就不要用Go了。
