If you have problems with special characters in URLS you can change function normalize_name in Outputfilter.seo.php with next lines:

Outputfilter.seo.php

	function _normalize_name($name, $search=false) {
		$this->_cur_name = '';
		$name = trim($name);
		$name=strtr($name,"┼▄▌ °·÷╔╣юабцдефгхийклмнопярстужьызшэщъЮАБЦДЕФГХИЙКЛМНОПЯРСТУЖЬЫЗШЭЩЪ",
			"SOZsozYYuAAAAAAACEEEEIIIIDNOOOOOOUUUUYsaaaaaaaceeeeiiiionoooooouuuuyy");
		if (!$search){
			$this->_cur_name = preg_replace($this->_norm_match, $this->_norm_repl, substr($name, 0, $this->_max_name_length));
			return strtolower($this->_cur_name);
		}else{
			$string = explode(' ',$name);
			$name = array();
			foreach($string AS $k=>$v){
				$name[] = $this->_normalize_name($v);
			}
			$name = substr(implode('+',$name), 0, $this->_max_name_length);
			$this->_cur_name = strtolower(str_replace('+',' ',$name));
			return strtolower($name);
			
		}
	}

	function _normalize_name($name, $search=false) {
		$this->_cur_name = '';
		$name = trim($name);

		$find = array("č"," ","·","Č","┼","▌","đ","Đ","ć","Ć");
		$replace = array("c","s","z","c","s","z","d","d","c","c");

		$name = str_replace($find, $replace, $name); 


		$name=strtr($name,"┼▄▌ °·÷╔╣юабцдефгхийклмнопярстужьызшэщъЮАБЦДЕФГХИЙКЛМНОПЯРСТУЖЬЫЗШЭЩЪ",

		if (!$search){
			$this->_cur_name = preg_replace($this->_norm_match, $this->_norm_repl, substr($name, 0, $this->_max_name_length));
			return strtolower($this->_cur_name);
		}else{
