Problem while printing Hindi text through a user defined function!

I how two php files one is main.php and second is functions.php. If I print below line in main.php, its working fine.

print "देश विदेश";

but my reqirment is to call a function from functions.php in main.php that should do the same:

Mian.php

require_once('functions.php');
print func_headline();

functions.php

function func_headline()
{
 //print html_entity_decode("देश विदेश", ENT_NOQUOTES,'UTF-8');
print "देश विदेश";
//utf8_encode("<a title='देश विदेश' href='#'><span>'दे开发者_如何学Pythonश विदेश'</span></a>");
}

why it doesnot works??

You need to just call the function in main.php. Change statement

print func_headline();

to

 func_headline();
