Get first character of UTF-8 string

by 
$first_char = mb_substr($title, 0, 1);

You need to use PHP’s multibyte string functions to properly handle Unicode strings:

http://www.php.net/manual/en/ref.mbstring.php

http://www.php.net/manual/en/function.mb-substr.php

You’ll also need to specify the character encoding in the <head> of your HTML:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

or:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-16" />
