使用 sf::st_read 读取形状文件无法捕获编码 UTF8

Question

我想读取一个用

UTF8

编码的形状文件。当我使用

rgdal::readOGR

读取它时效果很好，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，可以在此处下载我要读取的形状文件。

rgdal::readOGR

shp <- rgdal::readOGR(shp_file, encoding = "UTF-8")
head(shp@data)

# 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$NM_MUNICIP) <- "UTF-8"
sf$NM_MUNICIP

其他形状文件也会出现同样的问题，例如另一个，所以我认为这不是文件本身的问题。

Answer 1

当尝试使用编码为

sf::st_read

而不是

WINDOWS-1252

来读取它时，它对我有用。我希望它有帮助！UTF8
