Reproduce steps: 1. Emacs -Q 2. M-x eval-expression ``` (progn (setq cursor-type 'bar) (show-paren-mode 1)) ``` 3. Paste the following text in any .el file ``` (英文括号) (英文 括号) (中文括号) (中文 括号) ``` 4. Place the cursor at the first position (or last position) of each line. The expected behavior: All of the four lines above match and highlight correctly The actual behavior: The 4th line mismatched. Note the middle SPC character. P.s. 1. This issue only occurs in lisp-like modes. It is OK in c-mode and python-mode. 2. 【】「」『』have the same problem. They are also commonly used in lisp comment. 3. A simple investigation found that it may be related to `scan-sexps` or syntax-table, because `(scan-sexps outside dir)` in the `show-paren--default` returns the wrong value in the 4th case. 4.
