Thanks Eli - align-to 'space' display spec seems helpful.

Though it's a company specific issue related to unicode character
composition, here's some more details on the issue for record should
somebody else stumble upon the same.

Let's call the first character in the screenshot as shr (single glyph) and
the second one as sh-r (two glyphs).
(setq shr  (string 2358 2381 2352))
(setq sh-r (string 2358 2352))

(string-width shr)  ;; 2
(string-width sh-r) ;; 2

To create the rectangular region, we need to pad the strings with
appropriate number of spaces. align-to 'space' display spec seems helpful
in this case as shown below. You will notice that character "a" is aligned
in both cases. Now I need to figure out how to use the same within company.

(insert (concat shr
(let ((sp " "))
 (font-lock-append-text-property 0 1 'display `(space . (:align-to 10)) sp)
 sp)
"a"))

(insert (concat sh-r
(let ((sp " "))
 (font-lock-append-text-property 0 1 'display `(space . (:align-to 10)) sp)
 sp)
"a"))
