参考书目中出现多余的行

参考书目中出现多余的行

当我编写一篇很长的论文，其中包含很长的参考书目时，我注意到在参考书目的某些地方，条目之间添加了一行：

我尝试通过删除部分内容并进行编译来缩减文档和参考书目，以找出导致问题的原因。这花了我几个小时，下面的示例是我想出的最小示例。我想说的是，我知道这个示例可能不是“最小的”，但我确实试图让它尽可能小。

我在使用不同字体的参考书目中看到了这个问题，但由于问题似乎与间距有关，因此只有在使用最小示例中的参考书目时才会出现问题，如果我使用可以下载的 Brill Roman 字体进行编译这里。

我正在使用Mac OS Mavericks 上的后端xelatex进行编译。bibtexbiber

有人知道这里可能存在什么问题吗？

答案1

首先，请注意文件中有一些奇怪的重音字符.bib。例如，是普通重音字符(U+0065) 加上“组合重音”字符 (U+0301)é的组合，而不是普通重音字符 e (U+00E9)。eé

话虽如此，请注意，编译首先返回一个\hbox由文件中的“géographiques”一词引起的“Overfull”警告.bib，然后返回一个“Underfull \hbox”，这是导致多出一行的原因。

解决方案是告诉 LaTeX 如何用连字符连接单词“géographiques”，所有问题就都消失了。

因此，只需添加以下行

\hyphenation{géo-gra-phi-ques}

在序言中（希望连字符是正确的）解决了所有问题。
