Hi Ralph,

I don’t see any pixels in the PDF file when I typeset your code snipet (on MacOS 11.7.10). Here is what I get.

Instead of one bar there are now multiple characters attached to each other.

The bars look dotted, I guess it’s due to anti-aliasing (the dots disappear when anti-aliasing is disabled, but then of course everything looks pixelated). Two screenshots are attached (different zoom levels in PDF viewer) so that you know what I’m talking about.
