I have a Drupal 7 installation working with Oracle 11g database with Apache/2.2.12 (Linux/SUSE) and PHP/5.3.8
The problem I face is that special characters are not displayed correctly. Instead two question marks ('??') are shown.
I've been able to correct some static pieces of content (in blocks) converting the characters to their corresponding html entity. However, new content and menus dont support this.
I would like to know how to show those characters correctly.
