If you want to increment the letters through their respective ASCII code (see this list: http://www.asciitable.com/ ), you need to use an integer value and wrap the character in single quotes.

public OnFilterScriptInit()
{
    new Literka = 'A';
   
    for( ; Literka != 'Z'; Literka++)
    {
        printf("Char: %c - Decimal: %d", Literka, Literka);
    }
}
