如何解决R中的Devanagari脚本编码错误

编程问答 2022-06-06

问题描述

我有一个.csv文件，保存时是UTF-8编码的。该脚本是该文件中数据的梵文。我可以在excel中的csv文件中看到单词

में
लिए
किया
गया
हैं
नहीं
सिंह
पुलिस
दिया
करने
कहा
रहे
बाद
करें
साथ
रहा

但是当我在R中打开该单词时，这些单词无法正确编码。 print（）的输出是这样的：

                                                    word
                      सारे_खतरों_को
                जानते_हà¥\u0081à¤\u008f_भी
                                   विवेक_ने
                                             टीवी

我该如何解决？我尝试过Sys.setlocale()和read.delim(wordlist.csv,encoding = "UTF-8")，但都没有用。

解决方法

评论太久（对不起，我在R中是新角）：

print( sessionInfo())

library(stringi)
library(magrittr)

x <- read.delim("D:\\bat\\SO\\64497248_devangari.csv",encoding = "UTF-8")
print('=== print(x)')
print(x)
for (line in x){
  y <- line %>% 
    stri_replace_all_regex("<U\\+([[:alnum:]]+)>","\\\\u$1") %>% 
    stri_unescape_unicode() %>% 
    stri_enc_toutf8()
}

print('=== print(y)')
print(y)

print('=== for (i in y) {print(i)}')
for (i in y) {print(i)}

print('=== print(z)')
z <- x['word'] %>% 
  stri_replace_all_regex("<U\\+([[:alnum:]]+)>","\\\\u$1") %>% 
  stri_unescape_unicode() %>% 
  stri_enc_toutf8()
print(z)

输出（在Rgui.exe控制台中）：
