Escaping/Removing special characters when search runs

We have created a module for escaping/removing special characters when search query runs below.
It would be appreciated if this will be evaluated and included in the future Drupal Toolkit release.

Thanks.

-------------------------------
XC_Escape module

name = "XC Escape"
description = "Escape user input form"
core = "6.x"
package = "eXtensible Catalog (XC) System"

Setup:
1. Modify the code below("Code: Modification for xc_search.module") in the /sites/all/xc/xc_search/xc_search.module.
2. Copy xc_escape forder into "./site/all/module/xc".
3. Enable XC_Escape module on the administration (Site building >> modules).
/admin/build/modules
4. Setup the following preferences (eXtensible Catalog(XC) >> Seach Interface Setup >> Search Query Exceptions)
/admin/xc/search/escape_char

===========================================
Code: Modification for xc_search.module (around 2322 line)

1) Add the following codes into "function xc_search_form_search_validate"

if(module_exists('xc_escape')) {
$xc_remove_strings = xc_search_get_remove_strings();
foreach($xc_remove_strings as $xc_remove_string){
$values['keys'] = str_replace($xc_remove_string, '', $values['keys']);
}
$xc_escape_strings = xc_search_get_escape_strings();
$values['keys'] = stripslashes($values['keys']);
$flag_backslash = 0;
$xc_escape_strings = str_replace('\\','',$xc_escape_strings,$flag_backslash);
if($flag_backslash>0){
$values['keys'] = str_replace('\\', '\\\\', $values['keys']);
}
foreach($xc_escape_strings as $xc_escape_string){
$values['keys'] = str_replace($xc_escape_string, '\\'.$xc_escape_string, $values['keys']);
}
}

2) Add "xc_search_get_escape_strings()" function
/**
* Get escape strings from xc_escape_admin_settings
*
* @param none
* @return array
* escape strings
*/

function xc_search_get_escape_strings() {
$strings = array();
if (module_exists('xc_escape')) {
if(variable_get('xc_escape_select_type', null) == 0){
$strings = str_split(variable_get('xc_escape_strings', ''));
}
}
return $strings;
}

/**
* Get remove strings from xc_escape_admin_settings
*
* @param none
* @return array
* remove strings
*/

function xc_search_get_remove_strings() {
$strings = array();
if (module_exists('xc_escape')) {
if(variable_get('xc_escape_remove_select_type', null) == 0){
$strings = str_split(variable_get('xc_escape_remove_strings', ''));
}
}
return $strings;
}
