php - how to save an uploaded file named in persian characters with php?

Question

I want to replace the special characters by " " it means only alphabetical and numeric characters are supported, this code worked so far!

function clean($string) {
   return preg_replace('/[^A-Za-z0-9 ]/', ' ', $string);
}

but now when I try to allow persian (farsi) characters as well, the problem happens which is the $string becomes empty! and when I tried to use other examples given by users for example:

function clean($string) {
return preg_replace('/([^A-Za-z0-9 ])-(^[\x{0600}-\x{06FF}]*$)/', ' ', $string);
}

the file name saves as اذتاتا.

any ideas on how can I solve this?

thank you in advance!

我自己得到了答案，文件保存得恰到好处，问题是我的服务器没有 utf-8，所以它向我显示了这些字符，并且不得不限制用户只能使用英语和波斯语字母和数字我想出了这个解决方案：

$('input').keypress(function( e ) {    
    if(!/([ابپتثجچحخدذرزژشسصضطظعغفقکگلمنوهیء a-zA-Z0-9])+/.test(String.fromCharCode(e.which)))
        return false;
});
