在DiagrammeR中使用重音(utf8)

Question

我正试图使用优秀的图书馆图表与我自己的信息。但由于重音，我无法运行以下代码。有人知道我怎么传递这类单词吗?

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;
           ")

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;

根据Pascal的建议，我审查了https://github.com/rich-iannone/DiagrammeR/issues/124，并按照ssd3的建议使用了和ó的html代码。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;
           ")
