Yes, assuming that you are the server maintainer and thus have enough control of your php.ini configuration, you need to edit or override php.ini and disable those two lines.
Below is a copy& paste of what the area you need to adjust looks like in a typical php.ini file... the instructions before each switch will help you understand the implications:

register_globals = Off
... and
the Multibyte string conversion issue is already responded to here: http://drupal.org/node/207287

Ask them (!), or look through the hosters documentation.

I just put ini_set('register_globals', '0'); into the settings.php but it looks does not work.
