When I changed my english.php to define('CHARSET', 'utf-8'); in include/language/my_template/english.php, I can see other language format well in english environment, such as the record in chinese words in My Account's history. However, When I changed my english.php to define('CHARSET', 'utf-8'); in admin/include/language/my_template/english.php, I can't see other language format in Admin english environment. To solve it, I have to override the original english.php directly in admin/include/language/english.php........No override function in Admin control but work well in control of front website.

Any file I can copy from my source Zen Cart to fix the override problem for my admin control?
