How to count special characters function?

[briant]

I know the strlen function counts characters but not special characters. For example, I want this : êộờ to be only 3 characters, not 8 or whatever the strlen function gives.

I get a weird error when I use mb_strlen

Fatal error: Call to undefined function: mb_strlen() in /home/mysite/public_html/mypage.php on line 223


Here is my example:

echo mb_strlen('êộờ', 'UTF-8');
