Sure, but it could be made local to text-mode:
(modify-syntax-entry ?’ "w" text-mode-syntax-table)
(defconst my-text-char-script-table
(let ((table (copy-sequence char-script-table)))
(aset table ?’ 'latin)
table))
(defun my-text-mode-hook ()
(set (make-local-variable 'char-script-table)
my-text-char-script-table))
(add-hook 'text-mode-hook 'my-text-mode-hook)

Uff, I find these multiple variants of reference very confusing, I also
got a complaint from makeinfo that I was missing punctuation after the
first @xref. Does it look okay now? (I made the other wording fixes
too)
