使用 sf::st_read 读取形状文件无法捕获编码 UTF8
Reading shape file with sf::st_read fails to capture encoding UTF8
我想读取一个编码为 UTF8 的形状文件。当我使用 rgdal::readOGR 阅读它时它工作正常但 sf::st_read 无法获得正确的编码。关于如何解决这个问题有什么建议吗？
对于可重现的示例，可以下载我尝试读取的形状文件 here。

# I have also tried manually adding the encoding but it still doesn't work.
sf <- sf::st_read(shp_file, stringsAsFactors=F, options = "ENCODING=UTF8")
Encoding(sf$NM_MUNICIP) <- "UTF-8"

其他形状文件也会出现同样的问题，比如this other one，所以我认为这不是文件本身的问题。
当我尝试使用 sf::st_read 使用编码 WINDOWS-1252 而不是 UTF8 来读取它时，它对我有用。希望对您有所帮助！
sf <- sf::st_read("ac_municipios/12MUE250GC_SIR.shp", options = "ENCODING=WINDOWS-1252")
