Question

The problem is that when I use Youtube API to get a video (ex. video entry, feed, etc) it dose not show correct. for example:

الوسمي – المكتوب

appears like this

الوسمي – المكتوب

What is the cause of this, although english titles and content appears correctly ?

Answer 1

Try with UTF-8 charset on your page:

<?php
header("Content-Type: text/html; charset=UTF-8");
echo $video_title;

---

Using byte values from treating the weird characters you gave as windows cp1252:

<?php
header("Content-Type: text/html; charset=UTF-8");

$str = "\xd8\xa7\xd9\x84\xd9\x88\xd8\xb3\xd9\x85\xd9\x8a\x20\x2d\x20\xd8\xa7\xd9\x84\xd9\x85\xd9\x83\xd8\xaa\xd9\x88\xd8\xa8";

echo $str; //الوسمي - المكتوب  if the charset=UTF-8 is working

You can use the above code to always test if you are doing it correctly.
