            Bug ID: 170147
           Summary: Garbled text and font encoding issues when opening
                    PDFs created via "Print to PDF" drivers
           Product: LibreOffice
           Version: 26.8.0.0 alpha0+ master
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Draw
          Assignee: [email protected]
          Reporter: [email protected]

Description:
I’m reporting an issue regarding how LibreOffice Draw handles text in PDFs that
were generated using "Print to PDF" drivers (e.g., from a browser) instead of
being directly downloaded or exported natively.

When users choose to "Print to PDF" to save a pdf, the resulting file often
appears corrupted in Draw. The text is displayed as "garbage" (random symbols)
or renders with the completely wrong font.

The exact same files open and render perfectly in almost any other PDF viewer
(Adobe Acrobat, Chrome, Edge, etc.).

Even if I run the file through PDF repair tools, no errors are flagged, yet
Draw still fails to render the text correctly.

It seems like Draw is struggling to interpret the font encoding or subsets
created by these specific print drivers, making the file as "illegible" for
editing while others read it just fine.



Steps to Reproduce:
Steps to reproduce, open a web pdf.

instead of directly downloading it, use a "Print to PDF" driver to save it. 

Open the resulting file in LibreOffice Draw, Draw does not alert any issue when
opening it. 

Notice that the text is unreadable/garbled.


Actual Results:
Failure with printing from PDF to PDF, direct downloads without problems

Expected Results:
It should operate like readers that open printed PDFs from PDF to PDF without
any problems.  


Reproducible: Always


User Profile Reset: No
