Description

The width of separator character which is used to display horizontal rule is 2 in CJK language settings(Chinese, Korean, Japanese etc), so markdown-mode should consider its character width.

(set-language-environment "Japanese")
(char-width #x2500) ;; => 2

(set-language-environment "English")
(char-width #x2500) ;; => 1

Note

CJK users should set terminal configuration of ambiguous character width correctly. For example Gnome Terminal, set Ambiguous-Width Characters to Wide. If not, it looks like as below, the separator line is too short. Because char-width returns 2(full-width) but display width is 1(half-width).

If your terminal does not support CJK ambiguous characters, then you should remove such characters from markdown-hr-display-char like

(setq markdown-hr-display-char '(?-))
