您是否尝试过 read.csv（...，fileEncoding =UTF-8-BOM）？ ？file 说：

从R 3.0.0开始编码' -8-BOM'，并删除
a字节顺序标记（如果存在的话，它通常是由Microsoft应用程序生成的文件和网页
）。

As from R 3.0.0 the encoding ‘"UTF-8-BOM"’ is accepted and will remove a Byte Order Mark if present (which it often is for files and webpages generated by Microsoft applications).
