Problem With Unicode Language in Url

Hello, Tahmid.

I had the same problem.
Experience has shown a similar phenomenon in URI encoding with Korean.
So, not my plugin, but I checked Ajaxify’s history.js file.
As a result, I modified it as shown below, and the problem was solved in Korean.
Try it once.

m.unescapeString = function (b) {
	var c = b,
	d;
	for (; ; ) {
		// d = a.unescape(c);
		d = a.decodeURIComponent(c);
		if (d === c)
			break;
		c = d
	}
	return c
},

I’ve never worked with special characters such as Korean, Arabic or any of the non-english characters, but I’ve been using this and it’s been saving me several headaches. If you guys are willing, feel free to add to it (especially the dw_replaceChars function below!).

// Santize file uploads
function dw_safeFileUploads( $file ) {
	$file['name'] = dw_url( $file['name'] );
	return $file;
}
add_action('wp_handle_upload_prefilter', 'dw_safeFileUploads');

// Sanitize permalinks
function dw_cleanPermalink($url){
    $url = dw_url( $url );
    return $url;
}
add_filter('the_permalink', 'dw_cleanPermalink');

// The grunt work
function dw_url( $str = '' ) {
	$str = dw_replaceChars( $str );
	$str = strtolower($str);
	$str = trim($str);
	$str = preg_replace("/[\s-]+/", "-", $str);
	$str = str_replace("_", "-",$str);
	$str = preg_replace("/[^a-z0-9.-]/", "", $str);
	$str = str_replace("-.", ".",$str);
	return $str;
}
// Keep the replacement apart just to look cleaner
function dw_replaceChars($str) {
	$unwanted_array = array(
		' '=>'-', '?'=>'S', '?'=>'s', 'D'=>'Dj', '?'=>'Z', '?'=>'z', 'C'=>'C', 'c'=>'c', 'C'=>'C', 'c'=>'c',
		'à'=>'A', 'á'=>'A', '?'=>'A', '?'=>'A', '?'=>'A', '?'=>'A', '?'=>'A', '?'=>'C', 'è'=>'E', 'é'=>'E',
		'ê'=>'E', '?'=>'E', 'ì'=>'I', 'í'=>'I', '?'=>'I', '?'=>'I', '?'=>'N', 'ò'=>'O', 'ó'=>'O', '?'=>'O',

		'?'=>'y', 'R'=>'R', 'r'=>'r', "'"=>'-', '"'=>'-', '’'=>'-' );
	$str = strtr( $str, $unwanted_array );
	return $str;
}
