Strange urlencode results

[2CODE]

urlencode function returns a different results than if you copied the non-English words from the browser to the php file.

For example here's the results if I copied the non-english word from the browser :

%D9%85%D8%B5%D8%B1

And here's the result of the same word using the normal php urlencode :

%E3%D5%D1

And if I tried to decode these two results using urldecode it returns the same word correctly :bemused:

What's the problem ?

Different character encodings for the two files (the first one looks like UTF-8).

I thought that too, However I tried "mb_detect_encoding" but I found that they are the same UTF-8 ... 🙁
