定义命令来排版字符

Question

如果我运行下面的代码，则“Wesolowski”中的波兰语 L 不会排版。为了解决这个问题，我尝试定义一个命令来排版波兰语 L。在下面的代码中，我已在以下行中定义了该命令：

\newcommand{\PolishL}{l\llap{\raise0.2em \hbox{\tiny\slash}\kern-0.05em}}

但是这个命令仍然没有排版波兰语“L”

或者，有没有办法排版波兰语 L 而不必定义命令？

Answer 1

the open type导致您出现问题的原因可能只是/ font的真实名称truetype Lucida Sans。在我的系统上，它确实如此，Lucida Sans Unicode并且编译正常。

注意：我之所以评论是\addbiresource{refs.bib} 因为我没有。另外你不应该写\bibliography{refs}– 或者不要使用biblatex。
