Hi,

Why is the option `gnus-use-correct-string-widths' activated for
only XEmacs?

(defcustom gnus-use-correct-string-widths (featurep 'xemacs)
  "*If non-nil, use correct functions for dealing with wide characters."
  :group 'gnus-format
  :type 'boolean)

It should be t for all the people who read wide characters.  It
is not related to whether XEmacs is running or FSF Emacs is
running.

Sure it is. It costs in terms of performance and, at the time I debugged
and wrote the code that became that option and implementation, XEmacs
acted in a way that needed it which GNU Emacs didn't.

So, rather than have all the GNU Emacs people pay the additional cost of
using the slower code, it was enabled only for XEmacs.
