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. More screenshots and test code can be found in https://emacs-china.org/t/show-paren-mode/15160
