php - Question mark( �) displaying instead of each Bengali unicode character. How to fix it?

Friday 13 October 2017

The problem is confusing,such
as,

When I am trying to display a Bengali unicode
word,'কলম' with this


            $data=$_POST['data'];
 echo
            $data;

Then it displays the word
'কলম' properly as I
wanted,

But when I split the word character by character
with this

 for($i=0;$i<3;$i++)

            {
 echo $data[$i];
 echo "+";

            }

Then it display
'�+�+�+' instead of displaying like this
'ক+ল+ম+'.

How to solve this problem .Thank you.

For information , I have declared charset utf-8 in
head.
