I installed Noto fonts, and tried to set up fontset composed of
"Noto Sans Mono" and "Noto Sans Mono CJK JP Regular".
For some characters "Noto Sans Mono CJK JP Regular" has wide glyphs.
Evaluating the form below, only characters
#x00A7 #x00B1 #x00B6 #x00D7 #x00F7 #x02C7 #x02C9 #x02CA #x02CB #x02D9
are displayed with wide glyphs,
and other characters listed in the form are displayed with narrow glyphs.
(let ((base-font "Noto Sans Mono")
(alt-font "Noto Sans Mono CJK JP Regular")
(l '(#x00A7 #x00B1 #x00B6 #x00D7 #x00F7
#x02C7 #x02C9 #x02CA #x02CB #x02D9
#x2015 #x2016 #x2020 #x2021 #x2025 #x2027 #x2030
#x2035 #x203B #x2042 #x2051
#x2100 #x2103 #x2105 #x2109 #x210A #x210F #x2116
#x2121 #x2126 #x2127 #x212B #x2135 #x213B
#x221A #x221E #x2229 #x2248 #x2261 #x2264 #x2265
(#x2500 . #x25A0))))
(set-frame-font base-font)
(dolist (c l) (set-fontset-font t c alt-font)))
For example, C-U C-x = on #x00A7 shows in *Help* buffer:
character: § (displayed as §) (codepoint 167, #o247, #xa7)
display: by this font (glyph code)
uniscribe:-outline-Noto Sans Mono CJK JP Regular-normal-normal-normal-sans-13-*-*-*-p-*-iso8859-1 (#x66)
And C-U C-x = on #x25A0 shows in *Help* buffer:
character: ■ (displayed as ■) (codepoint 9632, #o22640, #x25a0)
display: by this font (glyph code)
uniscribe:-outline-Noto Sans Mono-normal-normal-normal-mono-13-*-*-*-p-*-ascii-0 (#x78E)
If 'face property with :family "Noto Sans Mono CJK JP Regular" attribute
is put on such characters, wide glyphs are displayed.

This makes "Noto Sans Mono" the default face's font, so it will be
used for any character supported by the font. If that's what you see,
then it's the intended behavior, AFAIK.

With '(setq use-default-font-for-symbols nil)', the glyphs are displayed
as I intended.
How can I find this variable?
And what characters are considered to be symbols and punctuation?

Good, then there's no bug here.
> How can I find this variable?
But you just did (with a bit of help from me).
If you are asking about its discoverability, then this variable is
supposed to be important in very infrequent situations, so it is not
very visible. As evidence to that effect, please note that by default
Emacs does display these characters, which is not a small feat for
Emacs to achieve, given that most fonts on Windows are not free.
> And what characters are considered to be symbols and punctuation?
Any character CH for which
(aref char-script-table CH) => symbol

I'm consequently also closing this bug report.
