It’s definitely a font issue - the same problem exists on macOS Sierra (if I change the message to Rich Text, such that the font used is Helvetica, I see the same dotted circle problem; the fixed-width font I use, SF Mono, does not have this problem…).

The best solution here may be to file a bug report at <> asking for font support, assuming the program you were using is using one of the Apple supplied fonts.

(Also, FYI, iOS applications can - and some do - install and use their own fonts.  It’s per-application, though; you can’t install them system-wide.)

Kind regards,
