However, when 2 width character is used, it detects the title line's width wrongly and breaks it even if the width is not too long. For example, when the title is "ＡＢＣＤＥＦ" (each character has width of 2), expected title would be like: ━━━━━━━━━━━━━━━ ＡＢＣＤＥＦ ━━━━━━━━━━━━━━━ However, the reality is: ━━━━━━━━━━━━━━━ ＡＢＣ ＤＥＦ ━━━━━━━━━━━━━━━ This is because it uses `length' to detects the width, which only returns the number of characters (6 in this case) but not the actual width displayed (12 in this case), and it tries to fill the line with that half width. `string-width' should be used instead. Here is a potential patch. --- ox-ascii.el.org 2021-03-26 09:28:44.000000000 +0900 +++ ox-ascii.el 2021-05-02 08:11:57.657347150 +0900 @@ -1033,7 +1033,7 @@ ;; Format TITLE.

Especially if this is done in a non-CJK locale, where the default font is likely to be different from the font used for double-width characters. The accurate method of lining up in these cases is to use window-text-pixel-size instead. That function will return the exact width of a string as it will displayed, in pixels, because it uses the same code as the display engine.

Would you mind giving an example about `window-text-pixel-size' usage in this situation? AFAIU, `window-text-pixel-size' returns the size of the window, but I fail to see how it is relevant here.

I see that `window-text-pixel-size' returns true displayed width but I think that's TRT for only the other bug I reported (bug#48149). These two bugs looks similar but the root causes are completed different. This bug (bug#48148) is actually caused by the difference of the width detection methods between line 1036 in ox-ascii.el (`length') and `fill-region'. This is because `org-ascii-template--document-title' first detects the title width by `length' and then tries to fill it by `org-ascii--fill-string' which does the action by `fill-region' inside. And since the filling point in `fill-region' is based on `move-to-column' and it looks like giving the same result as `string-width', I think `string-width' is TRT for this bug. In other words, specific to this bug, only the same width detection method as `fill-region' is required, even if it doesn't give you the precise width displayed. Please correct me if I am wrong. --- Shingo Tanaka On Sun, 02 May 2021 18:11:41 +0900, Eli Zaretskii wrote: > > > From: Nicolas Goaziou > > Cc: Shingo Tanaka , 48148@debbugs.gnu.org > > Date: Sun, 02 May 2021 10:23:34 +0200 > > > > > The accurate method of lining up in these cases is to use > > > window-text-pixel-size instead.

However, i don't think my misunderstanding is related to arguments of that function. >> AFAIU, `window-text-pixel-size' returns the size of the window > > No, it returns the size of _text_ when displayed in a window. True. My problem is that I have some string, _which is not displayed anywhere_ yet. I need to obtain its real width along with the width of a single character in order to compute the length argument in `make-string'. I may be missing something obvious. > I didn't mean text-width, I meant the use of string-width: it should > be replaced by a call to window-text-pixel-size. `string-width' applies to a string. `window-text-pixel-size' doesn't. This is the root of my misunderstanding, I guess.

The width of any text on display is meaningless unless you also tell in what window will it be displayed. That's because some of the factors that affect the display width depend on the window and the buffer shown by that window. So assuming the string you have will eventually be displayed in some window -- and most strings in Emacs are of that kind -- you should use that window up front. Otherwise, the value you get from other methods can only be an approximation, which will sometimes be close, and sometimes quite far from the truth.

Since it is the output of an export process, it could, e.g., be written to a file. I applied Shingo Tanaka's suggestion using `string-width', which is the best we can do considering our requirements. Thank you for your answer, and to Shingo Tanaka for the report an the patch.

However, when 2 width character is used, it detects the title line's width wrongly and breaks it even if the width is not too long. For example, when the title is "ＡＢＣＤＥＦ" (each character has width of 2), expected title would be like: ━━━━━━━━━━━━━━━ ＡＢＣＤＥＦ ━━━━━━━━━━━━━━━ However, the reality is: ━━━━━━━━━━━━━━━ ＡＢＣ ＤＥＦ ━━━━━━━━━━━━━━━ This is because it uses `length' to detects the width, which only returns the number of characters (6 in this case) but not the actual width displayed (12 in this case), and it tries to fill the line with that half width. `string-width' should be used instead. Here is a potential patch. --- ox-ascii.el.org 2021-03-26 09:28:44.000000000 +0900 +++ ox-ascii.el 2021-05-02 08:11:57.657347150 +0900 @@ -1033,7 +1033,7 @@ ;; Format TITLE.
