Public bug reported:
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.
