How can I save text form fields so they are correct everywhere

when I put long texts into a form using RPA.PDF.Set Input Fields, which are formatted to be multiline, this is not depicted as it should in any other browser than Firefox. However, I want to extend it, to work on all popular PDF viewers. I already tried changing the settings but nothing works. The PDF viewer gets that it should be formatted multiline, because when i click on it, it will configure it correctly.
Did anybody of you also had this problem and how did you fix it?
