Issues combining files together. With Windows 10 when I select multiple pdfs and right-click to select "Combine supported files in Acrobat" and select the files, there are issues merging files together and maintaining the correct characters (+, -, % & =). When I first create the pdf's, all characters show up correctly. I have attached a post from 2017 with exact same issue. Not sure why is shown as declined and there is no solution available? Please help me fix this issue.
