Redmine

This patch enables the CJK-friendly emphasis extension in commonmarker to properly parse Markdown emphasis (**) with CJK (Chinese, Japanese, Korean) characters. This resolves a known issue where emphasis marks were not correctly interpreted when adjacent to CJK characters, such as in **テスト。**テスト.

Input:

Before:

After:

I believe this will help improve the user experience for CJK language users.

According to the documentation for the package that this extension is based on, enabling it does not affect languages other than CJK.

This modification of the specification does not affect the other languages than Chinese, Japanese, and Korean. Even if your application or document has translations or content in other languages, it will not be affected

I have also verified its functionality with English, Spanish, and French, and found no issues. All tests have passed with this patch.
