using SC 4.83d3, Mojave, and a 2018 MacBook Pro Intel, when I use the shell function to put the man page for the unix cmd ls into a cd fld, SOME OF THE TEXT, in particular the headings of the various sections are INCORRECT - CHARACTERS ARE DUPLICATED.
But its not just the heading. Its not just upper case. For example look at the single line below the heading "SYNOPSIS" which contains errors in many kinds of characters BUT NOT ALL.
see the ATTACHED IMAGE which compares the accurate text in the terminal app and the aberrant text in cd fld 1
