   Doesn't happen for me . . .

   You are looking at the wrong places to try fixing this.  First, the
   default for OTHERCHARS in English and American dictionaries is "[']"
   (see ispell-dictionary-base-alist), and likewise for the "default"
   dictionary, so this already includes the apostrophe.

Yes, I see this.

   However, when ispell.el uses Hunspell, it doesn't use this database
   for OTHERCHARS; instead, it looks in the dictionary's affix file, see
   ispell-parse-hunspell-affix-file.  So you should look in your affix
   file and see if the apostrophe is mentioned there.  In my affix file
   for English, I see this line:

     WORDCHARS 0123456789'

   which includes the apostrophe.  See hunspell(4) man page for more
   details about the affix file and its settings.

Yes, this is my problem; the apostrophe was missing, and ispell DTRT
when I add it.  (I think I understand now what "different character
maps" means.)  Thanks for pointing me in the right direction.

   My affix file also has this line, which also includes the apostrophe:

     TRY esianrtolcdugmphbyfvkwzESIANRTOLCDUGMPHBYFVKWZ'-

   Not sure if it's relevant, but I though I'd mention it for
   completeness.

Mine has the apostrophe (though not the hyphen), so I left it alone.

   I see no bug in Emacs here.  ispell.el works as intended.

Agreed; this is probably an openSUSE config problem.  Unfortunately, I
can't file a bug with them because they are still shipping 27.2 (at
least in their openSUSE Leap 15.5 release) and I can't reproduce this
issue in that version.
