我试图保存从一个网站上下载的一些数据,其中包括一些汉字。我试了很多方法都没有成功。R studio默认文本编码设置为UTF-8,windows 10地区也设置为Beta,使用unicode UTF-8来支持全球语言。
##package used
library(jiebaR) ##here for file_coding
library(htm2txt) ## to get the text
library(httr) ## just in case
library(readtext)
##get original text with chinese character
mytxtC <- gettxt("https://archive.li/wip/kRknx")
##print to check that chinese characters appear
mytxtC
##try to save in UTF-8
write.csv(mytxtC, "csv_mytxtC.csv", row.names = FALSE, fileEncoding = "UTF-8")
##check if it is readable
read.csv("csv_mytxtC.csv", encoding = "UTF-8")
##doesn't work, check file encoding
file_coding("csv_mytxtC.csv")
## answer: "windows-1252"
##try with txt
write(mytxtC, "txt_mytxtC.txt")
toto <- readtext("txt_mytxtC.txt")
toto[1,2]
##still not, try file_coding
file_coding("txt_mytxtC.txt")
## "windows-1252" ```
For information
``` Sys.getlocale()
[1] "LC_COLLATE=French_Switzerland.1252;LC_CTYPE=French_Switzerland.1252;LC_MONETARY=French_Switzerland.1252;LC_NUMERIC=C;LC_TIME=French_Switzerland.1252" ```
我改了setLocal,好像可以用了.我只是在代码的开头加了这一行。Sys.setlocale("LC_CTYPE","chinese")
我只是在代码的开头加了这行: 只需要记得最终把它改回来。而且,我还是觉得很奇怪,这一行使得使用UTF-8保存成为可能,而之前是不可能的......
这对我来说在Windows上是可行的。
下载文件。
download.file("https://archive.li/wip/kRknx", destfile="external_file", method="libcurl")
输入文本 。
my_text <- readLines("external_file") # readLines(url) works as well
检查UTF8 :
> sum(validUTF8(my_text)) == length(my_text) [1] TRUE
你也可以检查文件。
> validUTF8("external_file") [1] TRUE
这里是唯一的 差异 我注意到,在Windows.NET系统中,我发现了一些问题。
user@somewhere:~/Downloads$ file external_file
external_file: HTML document, UTF-8 Unicode text, with very long lines, with CRLF line terminators
