Description Eyal Rozenberg 2022-09-30 10:02:43 UTC 
Reproduction instructions:

1. Create a new Writer document
2. Change the input language to Hebrew
3. Ensure the font family is David CLM (that's the default family LO chooses for Hebrew, and is bundled with LO), Regular weight
4. Type a phrase in Hebrew, e.g. שלום עולם
5. Export the document to a PDF (e.g. using File | Export As | Export As PDF)
6. Open the PDF in Writer or in Draw
7. Examine the font Writer uses for the text

Expected result: The opened PDF text is laid out in the David CLM font family, in regular weight.

The PDF may also exhibit bug 104597 (text run flipping), but we don't care about that here.

Actual Results: Writer tries to use a font family named "DavidCLMMedium", not "David CLM". The text is laid out in some fallback font.

To see the bug, just open this PDF (in Writer or Impress) and compare the font to what you see in the PDF itself. Or compare against the original document.

This doesn't happen for _all_ fonts, apparently. I tried some text in Noto Naskh and this didn't happen.

This should be a duplicate of bug 143095.

"DavidCLMMedium" is a PS font name LibreOffice has choosen when it exported to PDF, but failed to map this PS font name to the system font name at the of PDF import.
