Character encoding - naming codeigniter classes with other than latin characters

[eluser]mallix[/eluser]
Hello everybody,

its been a while that i am using CodeIgniter for developing web apps and so far it turns to be a handy one..

I was wondering if it is possible to give a name to a controller class and therefore a function, using Greek, Russian or German words like:

class Εργαλεια extends CI_Controller(){

function Εργαλεια(){
...
...
...
}

}

Is this possible? If anyone has a positive answer on this can we have here the steps to do so?

Thank you all in advance.

As of PHP: User-defined functions - Manual

Function names follow the same rules as other labels in PHP. A valid function name starts with a letter or underscore, followed by any number of letters, numbers, or underscores. As a regular expression, it would be expressed thus: [a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*.

Short answer: no
