PDF export bug – Unicode character "ł" (U+0142) corrupts text encoding of the entire PDF
I have found a reproducible issue in Adobe InDesign affecting PDF export.
Environment
Adobe InDesign 2026
Mac OS Tahoe 26.1
Font: Univers Next Pro Condensed (locally installed, licensed version)
Description
When exporting a PDF from InDesign, the presence of a single Polish lowercase letter ł (Unicode U+0142) causes the text encoding of the entire PDF to become corrupted.
The document displays and prints correctly, but copying text from the exported PDF no longer works correctly:
accented characters such as é, è, à, ê, ç, etc. are copied as periods (".") or incorrect characters;
the problem affects the entire PDF, not only the word containing ł.
Steps to reproduce
Create a new InDesign document.
Use Univers Next Pro Condensed.
Type the following text:
Libellułe
aeiéàè
Export the document as a PDF using the standard PDF export settings.
Open the PDF in Adobe Acrobat Reader.
Copy and paste the text into a text editor.
Expected result
The copied text should exactly match the original text, including all accented characters and the Polish character ł.
Actual result
The presence of the single character ł causes the PDF text encoding to become corrupted. Accented characters throughout the PDF are no longer copied correctly and are replaced by periods or incorrect characters.
