I'm not pretty sure but at least Japanese people seem to use
16-dot width font for Kanji if 8-dot width font is used for ASCII
(or 14-dot for Kanji and 7-dot for ASCII, etc.). And the fill
functions seem to have been designed assuming such a habit (i.e.,
Kanji font is twice the width of ASCII font). Though there seems
to be no help for text appearing uglily when using proportional
fonts.

Is there a reason not to use the fill functions? How about the
following?
--8<---------------cut here---------------start------------->8---
(defun shr-insert (text)
(when (and (eq shr-state 'image)
(not (string-match "\\`[ \t\n]+\\'" text)))
(insert "\n")
(setq shr-state nil))
(cond
((eq shr-folding-mode 'none)
(insert text))
(t
(if (string-match "\\`[\t\n ]+" text)
(setq text (substring text (match-end 0))))
(if (string-match "[\t\n ]+\\'" text)
(setq text (substring text 0 (match-beginning 0))))
(unless (string-equal text "")
(let ((start (line-beginning-position))
(fill-column shr-width)
(fill-prefix (make-string shr-indentation ? )))
(cond ((bolp)
(insert fill-prefix))
((eq (char-before) ? ))
((not (and (>= (char-width (or (char-before) ? )) 2)
(>= (char-width (aref text 0)) 2)))
(insert " ")))
(insert text)
(fill-region-as-paragraph start (point)))))))
--8<---------------cut here---------------end--------------->8---
It looks good enough to me for any language.
