In GNU sed we solved the same issue using texinfo's @codequoteundirected
and @codequotebacktick commands:

e.g.:

  @codequoteundirected on
  @codequotebacktick on
  @example
  $ echo hello world | sed 'y/abcdefghij/0123456789/'
  74llo worl3
  @end example
  @codequoteundirected off
  @codequotebacktick off

mentioned here:
https://www.gnu.org/software/texinfo/manual/texinfo/html_node/Inserting-Quote-Characters.html


Please note that these commands were introduced in texinfo 5.0.
If one wants to support older versions (e.g. 4.13 which is widely
available on BSDs and older systems), a small hack is required.
See lines 11 to 35 in sed's "config.texi":
https://git.savannah.gnu.org/cgit/sed.git/tree/doc/config.texi

Hope this helps,
