Encrypted PDFs with PDF version 1.6 and spaces in Password cannot be opened
Steps to reproduce:
- Open any PDF
- Encrypt the PDF with a password "12345 " and compatibility "Acrobat 7.0 and later" (128-bit AES)
- Save the PDF
- try to load it using MacOS preview or any other tool, and it will fail to open with the correct password.
Or, use an older version of Acrobat Pro (Say Acrobat 2020), encrypt with the password "12345 " and Acrobat 7.0 Compatibility, save it, and then try to load it with latest Acrobat Pro, and it will fail to open using the correct password

This prevents me from opening old encrypted PDFs, and I have to use other software, re-encrypt the PDFs using Acrobat X compatibility, and only then it will be saved correctly, and supported by every PDF software (including Acrobat Pro/Reader)
