r - 为什么 R 在加载库（tidyverse）时会显示 unicode 符号？

Question

我使用以下命令更新了 R 中的一些包 -

install.packages(c("BH", "DBI", "Matrix", "SparseM", 
                   "broom", "caTools", "callr", "cli", 
                   "curl", "data.table", "digest", "e1071", 
                   "foreign", "htmlTable", "igraph", 
                   "maptools", "multcomp", "nlme", "openxlsx", 
                   "plyr", "quantreg", "rmarkdown", "survival", 
                   "testthat", "tinytex", "vctrs", "webshot"))

在此之后，每次我加载 tidyverse 库（使用 library(tidyverse)）时，我都会得到以下输出。是否有任何更新的软件包导致此问题？我在网上找不到任何类似的问题/解决方案。我以前没有遇到过这个问题。

感谢任何输入。谢谢你。
