captivate 8: manifest file for scorm 1.2 generate enconding="utf-8" and when i upload to LMS the SCO Title change the portuguese characters

Hi, i'm working with captivate 8, and when i use scorm 1.2 / configuration, i write the SCO Title in portuguese charaters:

example: "Retenção"

when i publish the project, in zip file i have the manifest.xml file, with :

<?xml version="1.0" encoding="utf-8"?>

after i upload the project to the LMS and run the course in google chrome the word: "Retenção" appears with the portuguese characters changed: "çã" .... to others charaters... (i presume the utf-8 correspondent charateres)...

I try this:

After publish the zip file in my computer, i change the first line of the imsmanifest.xml:

from: <?xml version="1.0" encoding="utf-8" ?>

to:

<?xml version="1.0" encoding="unicode" ?> 

after this, i uploaded it to the LMS and this solve the problem.

But i d'ont want to edit xml files generated by the captivate 8 and change them every time i publish a project.

can anibody help me in order captivate 8 generate the  imsmanifest.xml with the correct encoding? i.e. "unicode"
