  ----CHARSET Settings----
 
 The settings below are used for various operations that are charset sensitive,
 for instance cleaning "user input".  The settings with # in front will need
 to be un-commented (remove the #) to use.  

 For "input cleaning", and anywhere else the PHP function htmlspecialchars()
 would normally be used, there is a 3 step process (below) to ensure that the
 data is not corrupted due to differences in charsets.  Note that step
 1 and 3 are skipped if the appropriate settings are not specified (Most sites
 will only need to set CHARSET_CLEAN, step 2):

 1. (Optional step, only run if CHARSET_FROM is set): The input's charset is
	converted from the CHARSET_FROM setting to the CHARSET_CLEAN setting.  It
	is converted either using mb_convert_string() or iconv(), according 
	to CLEAN_METHOD setting.
    
    See http://www.php.net/mb_convert_encoding for more information on setting
	CLEAN_METHOD to mb_convert_encoding.  CHARSET_FROM is used as the 3rd var passed
	to that function.  If CLEAN_METHOD is not set, and the function exists, 
	mb_convert_encoding is the default method used to convert the charset.
	
	See http://www.php.net/iconv for more information on setting CLEAN_METHOD
	to iconv.  CHARSET_FROM is used as the 1st var passed to that function.
	
	This step, and optionally step 3, are necessary in order to be able to
	clean any charset that is not compatible with the function 
	htmlspecialchars() (see step 2)
    
 2. (Always run): The input is "cleaned" using the PHP function htmlspecialchars()
    This step will use the CHARSET_CLEAN setting for the charset, that charset must
    be compatible with htmlspecialchars().
	
	This step is always run for security reasons, to prevent a certain type of
	hacking called "Cross Site Scripting" or XSS attack.  If the charset is not
	specified, or is not a compatible charset, the default of ISO-8859-1 is used.
    
    See http://www.php.net/htmlspecialchars for a list of compatible charsets you can
    use.
    
 3. (Optional step, only run if CHARSET_TO is set):  The cleaned input's charset 
	is converted from the CHARSET_CLEAN setting to the CHARSET_TO setting. It
	is converted either using mb_convert_string() or iconv(), according 
	to CLEAN_METHOD setting.
	
    See http://www.php.net/mb_convert_encoding for more information on setting
	CLEAN_METHOD to mb_convert_encoding.  CHARSET_TO is used as the 2nd var passed
	to that function, at this step.  If CLEAN_METHOD is not set, and the function exists, 
	mb_convert_encoding is the default method used to convert the charset.
	
	See http://www.php.net/iconv for more information on setting CLEAN_METHOD
	to iconv.  CHARSET_TO is used as the 2nd var passed to that function during
	this step.
