Bug: Bold text (**text**) not parsed when immediately followed by quotation marks

[kyle-ingka]

Bug Description

When using ** bold markers immediately followed by quotation marks (both straight " and curly "), the markdown parser fails to recognize the bold syntax.

Test Case

Input markdown:

效果**如何**？

我发现**"黑体"**展示不准确。

我发现**"黑体"**展示不准确。

我发现"**黑体**"展示不准确。

Expected Output

All four cases should render with bold text:

• 效果**如何**？ → <strong>如何</strong> ✅
• **"黑体"** → <strong>"黑体"</strong> ❌ (actual: **"黑体"**)
• **"黑体"** → <strong>"黑体"</strong> ❌ (actual: **"黑体"**)
• "**黑体**" → <strong>黑体</strong> ✅

Actual Output

<p>效果<strong>如何</strong>？</p>
<p>我发现**"黑体"**展示不准确。</p>
<p>我发现**"黑体"**展示不准确。</p>
<p>我发现"<strong>黑体</strong>"展示不准确。</p>

Root Cause

This is a limitation of the marked.js library used by wenyan. The parser requires certain boundary characters around the ** delimiters to recognize them as emphasis markers. When ** is immediately followed by a quotation mark, the parser doesn't recognize it as a valid emphasis boundary.

Environment

• wenyan-cli version: (current)
• Node.js version: N/A
• OS: macOS

Possible Solutions

1. Configure marked.js to be more permissive with emphasis boundaries
2. Add a preprocessing step to handle this edge case
3. Document this limitation and recommend users write "**text**" instead of **"text"**
