我正在尝试将优秀的库 Diagrammer 与我自己的信息一起使用。但是由于重音，我无法运行以下代码。有谁知道我怎样才能通过这种类型的词？

library(DiagrammeR)

DiagrammeR("
  graph BT;
           A(Entorno familiar)-->B(Desinterés)
           B-->C(Deserción);

           style A fill:#ffffff, stroke:#04C4AB, stroke-width:1.5px;
           style B fill:#ffffff, stroke:#04C4AB, stroke-width:1.5px;
           style C fill:#ffffff, stroke:#FF5E5E, stroke-width:1.5px;
           ")

我得到的错误是：

parse error with 
       graph BT;
       A(Entorno familiar)-->B(Desinter�s)
       B-->C(Deserci�n);

       style A fill:#ffffff, stroke:#04C4AB, stroke-width:1.5px;
       style B fill:#ffffff, stroke:#04C4AB, stroke-width:1.5px;
       style C fill:#ffffff, stroke:#FF5E5E, stroke-width:1.5px;

Maximum call stack size exceeded.

根据 Pascal 的建议，我查看了 https://github.com/rich-iannone/DiagrammeR/issues/124并按照 sdc3 的建议，我使用了 é 和 ó 的 html 代码。并且代码运行良好。

DiagrammeR("
           graph BT;
           A(Entorno familiar)-->B(Desinterés)
           B-->C(Deserción);

           style A fill:#ffffff, stroke:#04C4AB, stroke-width:1.5px;
           style B fill:#ffffff, stroke:#04C4AB, stroke-width:1.5px;
           style C fill:#ffffff, stroke:#FF5E5E, stroke-width:1.5px;
           ")
