thinkphp+iis6.0+win2003 验证码乱码

这个验证码非thinkphp自带的，该网站在本地电脑(win8.1)和其他win2003上正常显示，可传到服务器A就出现这错误
服务器A之前有使用过dz论坛，5.2.17 php版本，这要如何排错？请教，谢谢

$s = base64_decode('77u/R0lGODdhMgAWAKEAAN//fWRkZEFodQAAACwAAAAAMgAWAAACloyPqSmy/4CctAIhMcXa+mp8X1c1kylaYZpyF8mqQUyjtHyXJbyL65Wz2IRD0OzUSCaRNg4vs9xMfp6mxvpE+o6jKwmbLVKoQOjGexabP2TtrqgUvrZVHmoYr9N7/PVLPcfG5VeG15GXFmV0JnL3pRhEBQgFBzmCE9Q1eYKZSYSoFCo6SlpqmtWZ4Rm4GuAAAcvwGgtRAAA7');<br />echo bin2hex($s);

Copy after login

这个 efbbbf 就是 utf-8的 BOM 头
