Special characters in Scorm 1.2 (Swedish åäö)

Hi! I am trying hard to find a solution to read out special characters from our LMS (Totara) 

From the thread linked below, I found a solution for Scorm 2004 which is excellent but I want to use some of the functions coming with Scorm 1.2. I, therefore, wonder if anyone has a solution to this problem.

Swedish åäö (and other special characters are converted to underscore.

See examples:
