fopen创建中文TXT文件时出错

[standford]

$pagename="异路迷途.txt";
fp=fopen($pagename,"r");


这样后提示
Warning: fopen(异路迷途.txt) [function.fopen]: failed to open stream: Invalid argument in D:\code\book\phpcms\modules\book\index.php on line 44

Warning: fwrite() expects parameter 1 to be resource, boolean given in D:\code\book\phpcms\modules\book\index.php on line 50



如果是数字名称就可以

[码无边]

iconv("utf-8","gb2312",$filename);

[xuyanlu]

$pagename="异路迷途.txt";

$pathname = iconv("UTF-8", "gb2312", $pathname);
fp=fopen($pagename,"r");

字符集问题吧
