Here are the results including the one on Ubuntu.
Obviously, the 2nd one (Noto on Windows) returns a doubled-width size
which is unexpected.
;; On Windows - No issue
(progn
(set-face-attribute 'default nil :font "MS ゴシック")
(frame-char-width))
10
(string-pixel-width "A")
10
(string-pixel-width "あ")
20
;; On Windows - Wrong frame-char-width
(progn
(set-face-attribute 'default nil :font "Noto Sans Mono CJK JP")
(frame-char-width))
20
(string-pixel-width "A")
10
(string-pixel-width "あ")

;; On Ubuntu (w/Cairo) - No issue
(progn
(set-face-attribute 'default nil :font "Noto Sans Mono CJK JP")
(frame-char-width))
13
(string-pixel-width "A")
13
(string-pixel-width "あ")

Yes, the Emacs on Ubuntu is the latest Snap version which is compiled
with Cairo, as I can double check it by seeing colored Emoji.
