Here is a mistake, I do not know where to look. Launch site check - base in utf8 encoding, parameters:
mbstring.func_overload = 2 mbstring.internal_encoding = utf-8
Files of the catalog component converted to utf8 using the script described in the Bitrix community , setting the preliminary path to the folder.
define('START_PATH', $_SERVER['DOCUMENT_ROOT'].'/bitrix/components/bitrix/catalog/'); // стартовая папка для поиска Did not help. The main thing for me is this template. uni.loc \ bitrix \ php_interface \ after_connect.php file
Код $DB->Query("SET NAMES 'utf8'"); $DB->Query('SET collation_connection = "utf8_unicode_ci"'); $DB->Query('SET Character_set_results="utf8"');//my 

lang/ru/.parameters.phpcomponent and see how it is encoded. - u_mulder
