Now, this is really interesting

\starttext \textbar x\textbar \stoptext

On MacOS 10.13.6, using ConTeXt 1.02 of TeXLive 2018 updated using the TeXLive Utility, $|x|$, $\textbar x\textbar$, $\|x\|$, $‖x‖$, $||x||$ gives the output |𝑥|, |𝑥|, |𝑥|, ‖𝑥‖, ‖𝑥‖, copied from the PDF in Preview.

So it must be a bug with macOS Mojave 10.14.3 This is not surprising, as I have seen lots of other rendering bugs come and go with the Apple library. Alan
