This is a deliberate change in Emacs 25.1. Preferring the default face's font is better in the vast majority of cases, because it doesn't disrupt the text alignment. The preferred charset shown by "C-u C-x =" has nothing to do with selecting the font. (I also wonder what does a character such as u+2026 has to do with Japanese characters.) I've now added a variable that you can set to disable the new behavior and get back the old pre-Emacs 25.1 behavior, for those users who want/need that. The change is on the emacs-25 branch, so Emacs 25.2 will have it. With that, I'm marking this bug done. Thanks.

In order to give characters of each language a better appearance, I use a fontset that specifies a different font for ASCII characters and double-width Japanese characters. Since Emacs 25.1, however, I find that the default ASCII font is always used for some characters that belongs to some other character set (e.g. japanese-jisx0208) and for which another font is specified. (set-language-environment "Japanese") (set-face-attribute 'default nil :family "DejaVu Sans Mono" :height 96) (set-fontset-font nil 'japanese-jisx0208 (font-spec :family "TakaoGothic")) (add-to-list 'face-font-rescale-alist '(".*TakaoGothic.*" . 1.25)) When I launch Emacs with the "-Q" option and load the above settings, the default ASCII font is used for characters like #x2026 and #x25bd, though the result of describe-char shows that they belong to japanese-jisx0208: position: 80 of 4241 (2%), column: 44 character: … (displayed as …) (codepoint 8230, #o20046, #x2026) preferred charset: japanese-jisx0208 (JISX0208.1983/1990 Japanese Kanji: ISO-IR-87) code point in charset: 0x2144 script: symbol syntax: _ which means: symbol category: .:Base, >:Not at bol, c:Chinese, h:Korean, j:Japanese to input: type "C-x 8 RET 2026" or "C-x 8 RET HORIZONTAL ELLIPSIS" buffer code: #xE2 #x80 #xA6 file code: #xE2 #x80 #xA6 (encoded by coding system utf-8-unix) display: by this font (glyph code) xft:-unknown-DejaVu Sans Mono-normal-normal-normal-*-13-*-*-*-m-0-iso10646-1 (#x728) Character code properties: customize what to show name: HORIZONTAL ELLIPSIS general-category: Po (Punctuation, Other) decomposition: (compat 46 46 46) (compat '.' '.' '.') Emacs 24 uses for these symbols the font specified for japanese-jisx0208 and displays them as double-width Japanese symbols. When displayed with the default ASCII font as in Emacs 25, these symbols give Japanese texts a rather awkward appearance. The same issue is discussed in the thread starting with the following message: http://lists.gnu.org/archive/html/help-gnu-emacs/2016-10/msg00004.html I agree with Alex that there should be some way to override the default ASCII font, especially because in my case it considerably alters the appearance of the text. I would appreciate it if some customization could be made possible. Best regards.
