Comment 7 for bug 1774244

Description:
In this example, I created a document with a few Arabic-script characters (U+08A2, U+08A3 & U+08A4), which were quite recently added to Unicode for various Arabic-script African languages such as Fulfulde. The font I had used in the rest of the document was DejaVu Sans, so I used that font setting even for these characters. In reality, these glyphs are not found in DejaVu Sans but had to be substituted from another font, in my case Scheherazade (from fonts-sil-scheherazade, available through packages.sil.org). After rotating the letters by 90 degrees, everything looked fine on the screen but when I created a PDF, everything was displaced about one inch upwards and one inch to the left. See the attached screenshot, where everything looks fine, and the PDF where all the letters are displaced.

If I change the font setting for this text to Scheherazade, everything looks fine even in a generated PDF. So apparently LibreOffice gets confused by the different font metrics of the two fonts, the one selected by the user and the one used as the real source for the glyphs.

This bug was first reported on Launchpad for LO 5.4.6.2 on Ubuntu 17.10 at: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1774244 . After my initial report, I have upgraded to LO 6.0.3.2 and can still reproduce the problem. Another user on Launchpad confirmed the bug on LO 6.0.3.2 and 6.1.0.3 on Ubuntu 18.04, as well.

Steps to Reproduce:
1. In a new Writer document, type Arabic characters that are not present in the default font (in my example "ࢢࢣࢤ").
2. Select the text and rotate it by 90 degrees through the Font properties dialog.
3. Generate a PDF.

Actual Results:
In the generated PDF, the text is displaced one inch to the left and one inch upwards. In Writer everything looks fine.

Expected Results:
The generated PDF should look the same as the document view in Writer.

Reproducible: Always
