A [micromark](https://github.com/micromark/micromark) extension to make GitHub Flavored Markdown (GFM) strikethrough (`~~`) compatible with Chinese, Japanese, and Korean (CJK).
GitHub Flavored Markdown（GFM）の取り消し線記号（`~~`）を日本語・中国語・韓国語にきちんと対応させるための[micromark](https://github.com/micromark/micromark)拡張
一个 [micromark](https://github.com/micromark/micromark) 扩展，用于使 GitHub Flavored Markdown（GFM）的删除线标记（`~~`）能够正确支持中文、日语和韩语文本。
GitHub Flavored Markdown(GFM)의 취소선 기호(`~~`)를 한국어, 일본어, 중국어와 호환되도록 만드는 [micromark](https://github.com/micromark/micromark) 확장.
## Problem / 問題 / 问题 / 문제
CommonMark has a problem that the following emphasis marks `**` are not recognized as emphasis marks in Japanese, Chinese, and Korean.
CommonMarkには、日本語・中国語・韓国語内の次のような強調記号(`**`)が強調記号として認識されない問題があります。
CommonMark存在以下问题：在中文、日语和韩语文本中，强调标记`**`不会被识别为强调标记。
CommonMark는 한국어, 일본어, 중국어에서 다음과 같은 강조 표시 `**`가 강조 표시로 인식되지 않는 문제가 있습니다.
```md
**このアスタリスクは強調記号として認識されず、そのまま表示されます。**この文のせいで。
**该星号不会被识别，而是直接显示。**这是因为它没有被识别为强调符号。
**이 별표는 강조 표시로 인식되지 않고 그대로 표시됩니다(이 괄호 때문에)**이 문장 때문에.
```
This problem occurs because the character just inside the `**` is a (Japanese or Chinese) punctuation mark (。) or parenthesis and the character just outside is not a space or punctuation mark.
これが起こった原因は、終了側の`**`のすぐ内側が約物（。やカッコ）、かつ外側が約物や空白以外の文字であるためです。
这个问题是因为在`**`的结束部分，内侧字符是标点符号（。）或括号，而外侧字符不是空格或标点符号。
이 문제는 `**` 바로 안쪽의 문자가 (일본어나 중국어) 문장 부호(。) 또는 괄호이고 바깥쪽 문자가 공백이나 문장 부호가 아니기 때문에 발생합니다.
Of course, not only the end side but also the start side has the same issue.
もちろん終了側だけでなく、開始側も同様の問題が存在します。
当然，不仅是结束侧，开始侧也存在同样的问题。
물론 끝나는 부분뿐만 아니라 시작하는 부분에서도 동일한 문제가 있습니다.
CommonMark issue: https://github.com/commonmark/commonmark-spec/issues/650
This behavior is also applied to the strikethrough (`~~`) in GFM.
この挙動は、GFMの取り消し線（`~~`）にも該当します。
这个行为也适用于 GFM 的删除线（`~~`）。
이 동작은 GFM의 취소선(`~~`)에도 해당됩니다.
