Regular Expression Fix

Hi. A regex used in PhpDig versions 1.6.3 and 1.6.4 does not permit certain characters like ß in a search. To fix this do the following.

In search_function.php find:
PHP Code:
if (eregi("[^[:alnum:]^ +^-]+",$query_to_parse)) { $query_to_parse eregi_replace("[^[:alnum:]^ ]+"," ",$query_to_parse); } 
and replace with the following:
PHP Code:
$what_query_chars "[^".$phpdig_words_chars[PHPDIG_ENCODING]." -]+";
if (
eregi($what_query_chars,$query_to_parse)) {
    
$query_to_parse eregi_replace($what_query_chars," ",$query_to_parse);

Also in search_function.php find:
PHP Code:
// init variables 
and right after add the following:
PHP Code:
global $phpdig_words_chars
