win7 write_var_len function write 10('/n') translate '/r/n'

[gzjiangying]

win7上 write_var_len函数 写入10('/n') 会被转义为'/r/n'，导致文件编码错误，我不知道为什么下载的EXE没有这个问题但是自己编译的就有这个问题。
Writing 10('/n') to the write_var_len function on win7 can be escaped to '/r/n', resulting in a file encoding error.I don't know why the downloaded EXE doesn't have this problem but the compiled one does.
