Description al F 2023-06-30 15:36:57 UTC 
SUMMARY
When clicking "show forms" and filling in, everything looks fine. However, clicking "Show forms" again after filling in text, `æ` and `å` just disappears while `ø` is changed to `ł`. If filling in `ł` it disappears.

Font sizes are also distorted, it seems Okular adjusts the size to fill each form entirely, rendering the document layout ugly. Printing uses the wrong display, even if forms are currently showing the correct characters.

STEPS TO REPRODUCE
1. Download https://www.politiet.no/globalassets/02-tjenester-admin/politiattest/bekreftelse-pa-formal-med-soknad-om-politiattest.pdf
2. Open with Okular and click "Show forms". Fill in text containing special characters (the Norwegian æ, ø, å or others like ł or µ)
3. Click "Show forms" again.

OBSERVED RESULT
Text is incorrectly displayed and printed

EXPECTED RESULT
Text should be correctly displayed and printed

ADDITIONAL INFORMATION
