使用UTF-8编码的read.csv() [英] read.csv() with UTF-8 encoding
问题描述
我正在尝试从csv文件中读取数据，并将字符编码指定为UTF-8.通过阅读?read.csv()指令，似乎将fileEncoding设置为UTF-8即可完成此操作，但是，在检查时我看不到这一点.导入数据时，是否有更好的方法将字符串的编码指定为UTF-8?
I am trying to read in data from a csv file and specify the encoding of the characters to be UTF-8. From reading through the ?read.csv() instructions, it seems that fileEncoding set equal to UTF-8 should accomplish this, however, I am not seeing that when checking. Is there a better way to specify the encoding of character strings to be UTF-8 when importing the data?
样本数据:
fruit<- read.csv("fruit.csv", header = TRUE, fileEncoding = "UTF-8")
fruit[] <- lapply(fruit, as.character)
Encoding(fruit$Fruit)
输出为未知"，但我希望它为"UTF-8".确保所有导入的字符均为UTF-8的最佳方法是什么?谢谢你.
The output is "uknown" but I would expect this to be "UTF-8". What is the best way to ensure all imported characters are UTF-8? Thank you.
推荐答案
fruit <- read.csv("fruit.csv", header = TRUE)
fruit[] <- lapply(fruit, as.character)
fruit$Fruit <- paste0(fruit$Fruit, "\xfcmlaut") # Get non-ASCII char and jam it in!
Encoding(fruit$Fruit)
[1]"latin1""latin1""latin1"
[1] "latin1" "latin1" "latin1"
fruit$Fruit <- enc2utf8(fruit$Fruit)
Encoding(fruit$Fruit)
[1]"UTF-8""UTF-8""UTF-8"
[1] "UTF-8" "UTF-8" "UTF-8"
