In case anyone has a similar problem and finds this thread. as an opinionated user I feel it would make the most sense for me to always have a consistent ambiguous CJK character setting between my terminal and Emacs, so that the text layout for Emacs under terminal never breaks for any of those characters. I've added the following to my .emacs now (as all my terminals has defaulted to half width for years): ;;; half width CJK ambiguous characters (same as most terminal ;;; defaults) (setopt cjk-ambiguous-chars-are-wide nil)

I eventually decided to go with the more conservative approach of removing the two characters used by whitespace-mode from the list of ambiguous-width characters. This change is not installed on the emacs-30 branch, so the next Emacs release should have this problem fixed.

(Since I tested them and saw how wide the middle dot was) And some of them don't even offer an option to change it to full width.

The fonts I'm using, and most Chinese Linux users may be using (to my understanding), are: - WenQuanYi (WQY) fonts - Noto (i.e. Source Han, a different branding) fonts See also https://wiki.archlinux.org/title/Localization/Chinese The WenQuanYi fonts have a much longer history and the middle dot is always half width in them (checked just now). I'm currently using WenQuanYi Micro Hei. The Noto/Source Han fonts are relatively new and have an interesting situation where the Noto Sans CJK SC/TC have the middle dot as full width but Noto Sans CJK JP/KR have it as half width. Some Microsoft proprietary system-default fonts for Chinese characters, e.g. SimSun and SimHei, also have the middle dot as full width, but I guess few Linux users would be using it. I should also mention that some CJK users prepend an English font before their CJK font for usage in UI/terminal, because English fonts usually contain better quality glyphs for latin letters than the ones embedded in CJK fonts - essentially they only use the CJK-only part of the CJK fonts. So the middle dot will always be half width for them. > I'm wondering why we didn't hear > by now complaints from CJK users about the effects of > cjk-ambiguous-chars-are-wide other than on whitespace-mode.

Emacs 30 is still new-ish, e.g. it landed in Arch Linux stable on Feb 25, only two weeks ago 2. Not a lot of CJK users set a CJK locale ($LANG) for their terminal - they usually set it for the DE but not necessarily in /etc/locale.conf for the entire environment, because that means localized messages won't appear properly under TTY with its default font. I did that because I would manually set LANG if I actually have to use TTY instead of a terminal emulator some day.

Not necessarily. I still haven't decided what would be the best
solution for that, but telling users to sett
cjk-ambiguous-chars-are-wide to nil for the benefit of whitespace-mode
is definitely not high on the list, because the effects of that
variable are global on the entire Emacs session. I'm asking these
questions in order to understand better the issues and the possible
solutions.
Currently, the two solution I'm pondering are:
. remove from the list of ambiguous-width characters some of the
characters with low Unicode codepoints, including the 2 characters
used by whitespace-mode, on the assumption that these characters
are unlikely to be full-width in fonts used by Emacs users in CJK
locales
. change the default of cjk-ambiguous-chars-are-wide to nil, on
the assumption that most users in CJK locales use fonts where
these characters have half-width glyphs

OK, so in any case, we should extend the doc string of
cjk-ambiguous-chars-are-wide to mention the possible need to customize
the terminal emulator to draw the ambiguous-width characters according
to the font that is actually being used.
Thanks. Let me think a bit more about what would be the best
solution. But could you tell which font you used that has full-width
glyphs for these characters? Is it unusual to use that font for
terminal emulators in CJK locales? I'm wondering why we didn't hear
by now complaints from CJK users about the effects of
cjk-ambiguous-chars-are-wide other than on whitespace-mode. Maybe the
other ambiguous-width characters are seldom used in practice? Or
maybe too little time has passed since Emacs 30 was released?

Does that mean the solution should be users who use a CJK locale will need to set cjk-ambiguous-chars-are-wide to nil in order for whitespace-mode to work? It seems to me this might mean most users with a CJK locale will need to do that if they ever use whitespace-mode, because it never makes sense for the whitespace replacement char (the middle dot) to occupy the space of two characters. > Hmm... does gnome-console have any configuration options for this?

I can confirm this does allow the middle dot to show up as two characters wide (even without a font change), which looks strange but does make line wrapping and editing work.

I can confirm this does make the issue go away. But looking at the NEWS announcement for cjk-ambiguous-chars-are-wide, it seems to suggest the previous default was already full-width, which conflicts with the fact that whitespace-mode was working fine in terminal in Emacs 29.4 under a CJK locale. So was there an unintentional default behavior change, and should that be fixed? > Can you look for a font where the characters U+00B7 MIDDLE DOT and > U+00A4 CURRENCY SIGN have fullwidth glyphs?

No, the same issue persisted and the only difference is that this time only the first half of the full-width middle dot was rendered.

This must be done either via setopt or interactively via customize-option, not via setq. Does the problem go away if you do that, and then turn on global-whitespace-mode?

I want to add some more tests that I did, with en_US.UTF-8 and zh_CN.UTF-8 enabled in my /etc/locale.gen : 1. env -i TERM=$TERM LANG=zh_CN.UTF-8 emacs -nw -q shows the issue; 2. env -i TERM=$TERM LANG=zh_CN.UTF-8 LC_CTYPE=en_US.UTF-8 emacs -nw -q doesn't show the issue; 3. env -i TERM=$TERM LC_CTYPE=zh_CN.UTF-8 emacs -nw -q shows the issue again. So I believe this is an issue that more precisely happens when LC_CTYPE is set to a CJK locale. And I tried the tests above under tty (which uses the kerner default font) and got the same result. So I'm relatively confident this issue is unrelated to my fonts now.

Thanks for the reply. I did some further debugging and found out this issue also disappears on 30.1 if I set my LANG=en_US.UTF-8 , whereas my current env is LANG=zh_CN.UTF-8 . The same issue still exists if I set LANG=ja_JP.UTF-8 . (I do have all the three locales enabled in my /etc/locale.gen .) So I suspect this might be a regression in 30.1 (compared to 29.4) about logic handling full/half width characters under terminal for the whitespace-mode characters (e.g. middle dot) when LANG is a CJK locale. I also tried to identify if this issue is related to my font configuration, but the issue still happened when I prepended `DejaVu Sans Mono` to my `monospace` font and verified that it became my terminal font. So I think this issue is less likely related to my font.

Inserting new characters also results in characters after the insertion to drift right further than necessary and makes it impossible to properly edit a document. The amount of drifting seems to be related to the number of whitespace characters shown by whitespace-mode. A image showing the bug is available at https://imgur.com/a/PWbFgyE . I verified that this issue occurs with `emacs -nw -q` (so that my .emacs isn't interfering) and the `*scratch*` buffer (its vanilla English-only content) using `M-x global-whitespace-mode` on Emacs 30.1 runnin under gnome-terminal, gnome-console and foot (the Wayland terminal emulator) on most recent Arch Linux running GNOME 3 on Wayland. My locale is zh_CN.UTF-8 and my terminal font, i.e. the `monospace` font, is set to `WenQuanYi Micro Hei Mono` (=E6=96=87=E6=B3=89= =E9=A9=BF=E7=AD=89=E5=AE=BD=E5=BE=AE=E7=B1=B3=E9=BB=91 in Chinese, part of the wqy-microhei Arch Linxu package), if that matters. Downgrading to Emacs 29.4 immediately solved this issue so I believe it is a regression. Here's a screen recoding and the coresponding termscript of this issue: - Video: https://imgur.com/a/IhA8JxD - Termscript: https://files.catbox.moe/tskpy8 I've also attached some environment info and output from `M-x report-emacs-bug` below, and hopefully they can be helpful in debugging this.Thanks in advance!
