[quote author="jalalski" date="1234563702"]on my install I have (in application/config/config.php line 80)
$config['charset'] = "UTF-8";
maybe you didn't copy over the config files?[/quote]
I followed the help instructions to upgrade from CI 1.7.0 to CI 1.7.1 and the requirements were to just copy the system directory.
I have just checked in CI 1.7.0 config.php file and the $config['charset'] is set. It looks as though I did not upgrade my last version correctly.
Many thanks for your help.
