我排版我的日记只是为了好玩。我使用scrartcl有两列的 KOMA 脚本。我正在使用 LuaLaTeX 和 XeLaTeX 进行测试。我没有注意到两种渲染之间的页数不同，XeLaTeX 渲染的页面更多，116 页 vs 114 页 A5 页面。我注意到两个引擎的连字符方式有所不同。以下是我的图表列表中的一个例子：
如您所见，XeLaTeX 决定将单词“démoni”连字符化，但结果在第三行出现了一个大漏洞。上图是一个极端的例子，但总体而言，LuaLaTeX 结果似乎比 XeLaTeX 结果包含的此类漏洞更少。
另一方面，在其他地方（实际上在同一页面上），LuaLaTeX 对 4 行段落的前三行连续行进行了连字符处理，这似乎也不理想，而 XeLaTeX 选择仅对前两行连续行进行连字符处理。
- 如此巨大的差异是预料之中的吗？有人能描述一下这些差异吗？或者给我链接一下这些差异的描述吗？
- 有没有办法让两个引擎的结果更加接近呢？
不是 MWE，只是我文档的序言。它是 Pandoc 生成的用于转换为 LaTeX 的修改版本：
