People often copy/paste *from* a PDF document. When using certain fonts in LibreOffice, and exporting to PDF, then copy/paste from that PDF, the resulting text has all sorts of character replacements.
Steps to Reproduce:
1. Create YourDocument.odt
2. Use Calibri font (default for MSWord, often requested for resumes), or Carlito (metric equivalent to Calibri)
3. Export as / Export as PDF / save (as) YourDocument.pdf
4. Open YourDocument.pdf
5. Select text / copy text / paste text into notepad
Characters have been replaced with garbage characters.
Now change the font to Times New Roman/Arial/Courier New. Problem disappears.
Pasted text should be what is visible in the PDF document created by LibreOffice Writer.
