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.
