Fatal error: Call to undefined function r()

I am getting the Fatal error: Call to undefined function r() … on my Wordpress blog.
No function is there. The line there is the below.
remove_action(‘wp_head’, ‘wp_generator’);

I am getting strange error in functions.php file of my theme. It is giving Fatal error for many places where there cannot be any error. What to do?

Please help!

I have recently made changes to my blog and this is happening after I have set up every thing correctly. I doubt if this is a attack!
Could it be due to cache plugin? It has created a panic button on my mind.

That was the message.
When I delete three lines from there then it comes to long long below and tell about this line:
if (! function_exists(‘tagBreadCrumb’)) {

Fatal error: Call to undefined function r() in /XXXX/XXXX/public_html/wp-content/themes/simple/functions.php on line 5

Got the solution.
It was the utf-8, I used at the time of file saving.

It seems that it is in the plugin file. I am not sure which plugin it is. So check in the function wp_generator(). In that function the function r() is used or there is something misunderstanding. Can you post your whole error message here?

The error message itself clearly says that the function r() is used somewhere in your page (it must have given you the file name along with error message where the function is used) which is not defined anywhere. So see on that page and comment out the function r() if it is really not needed for you.

No dear, there is no function like that. and as I said the code on that line is 
remove_action('wp_head', 'wp_generator');
