Dear Mitshuaru,
thank you for your prompt reply and clear instructions - this is very
helpful for me as I don't have any experience with lldb!
> Could you try the following instructions?

(lldb) p file
(FcChar8 *) $0 = 0x00000001071522e0 "/System/Library/Fonts/ArabicUIDisplay.ttc"
The file exists
: leinen@macsl[leinen]; ls -l /System/Library/Fonts/ArabicUIDisplay.ttc
-rw-r--r-- 1 root wheel 983632 Aug 18 2018 /System/Library/Fonts/ArabicUIDisplay.ttc
Maybe the code has issue with right-to-left scripts?

Simon.
