使用 ISO-8859-1 编码而不是 UTF-8 导出 csv

Question

I struggle with encoding in csv exports. I'm from the Netherlands and we use quite some trema's (eg ë , ï ) and accents (eg é , ó ) etc. This causes troubles when exporting to csv and open file in excel.

On macOS Mojave.

I've tried multiple encoding functions like the following.

library(stringr)
library(readr)

test <- c("Argentinië", "België", "Haïti")

test %>%
  stringi::stri_conv(., "UTF-8", "ISO-8859-1") %>%
  write.csv2("~/Downloads/test.csv")

But still, this causes weird characters:

Answer 1

How do I take care of people importing the right encoding in their Excel..?

Don't convert to iso-8859-1 but export with readr::write_excel_csv2() . It writes the file as UTF-8, but with byte order mark (BOM) , which Excel understands).

library(readr)
test <- c("Argentinië", "België", "Haïti")

I need to convert test to UTF-8, because I am on Windows.

test <- enc2utf8(test)

On MacOS test should be in UTF-8 already, as that is the native encoding.

Encoding(test)
#> [1] "UTF-8" "UTF-8" "UTF-8"

Save as an Excel csv with readr::write_excel_csv2()

write_excel_csv2(data.frame(x = test), "test.csv")

Alternatively save as xlsx with writexl::write_xlsx()

writexl::write_xlsx(data.frame(x = test), "test.xlsx")

Answer 2

test <- c("Argentinië", "België", "Haïti")

con <- file('~/test.csv', encoding = "ISO-8859-1")

write.csv(x = test, file = con)

A call to csvlook test.csv -e "ISO-8859-1" in my bash returns | a | x | | - | ---------- | | 1 | Argentinië | | 2 | België | | 3 | Haïti | | a | x | | - | ---------- | | 1 | Argentinië | | 2 | België | | 3 | Haïti |

Answer 3

do the simple thing

Just open the file in note pad and save as UTF -8 in another name, now open the saved notepad file in excel and it will ask you import, do delimiter based on your report and use , also as delimiter for columns separation and finish import. you will get your clean file
