As requested by Klaus on the forum thread
isn't a bug.
TL;DR version - extracting text from PDFs is hard, and viewers all do it
differently with different levels of 'correctness'.
The fonts used and the layout can affect what they can produce.
In this case, the stack in question was being printed with the default
system theme fonts (on macOS this is .SFNSText it would seem) - and for
whatever reason that font generates glyphs for numbers in the PDF which
PDF viewers don't seem to be able to map back to actual digits.
Upshot - make sure the controls you are printing have an explicit font
setting to a 'normal' font if you want to be able to copy text from any
PDF you might generate as a result :)
