Thank you for the link! It seems very comprehensive and must be useful
for many other issues, too.
I agree the bug I reported isn't a big issue.

After my last message, I learned that Ruby has abandoned the idea of
"character type" and instead of elevating ?a to a proper character
literal, it has made it equivalent to a single-character string "a".
So, a String is no longer a sequence of individual characters (because
"character" has no representation in the language). "a".ord returns
the character code of this single-character string but "abc".ord
ignores the "bc" part. I don't think that's a clean design, but
perhaps it's the simplest, practical one, in the face of various
character encodings. . . . That makes me wonder how Haskell handles
unicode. In that language, "String" is an alias for "[Char]" (list
of Char's). . . . I digressed.
