only UTF-8, but im unsure why then links are not added to words when they contain some of ě?čř????? characters.. so there is no way to modiffy

//    $bopfind = preg_quote (htmlspecialchars($bopfind));
      define('CHARSET', 'ISO-8859-2');
      define('REPLACE_FLAGS', ENT_COMPAT | ENT_XHTML);  
      $bopfind = preg_quote (htmlspecialchars($bopfind,REPLACE_FLAGS, CHARSET));

or any other part of the code so it work?
