我有一个包含英语和法语单词的原始文本向量，因此有法语单词有重音字符，如下所示：
1 entretien ménager
2 concepteur réseaux
3 service à la clientèle
4 sécurité
5 infirmière auxiliaire
6 opérateur de machinerie en usine
7 consultant stratégique
8 ménage
9 ingénieur civil, gérant projet
10 éducatrice
命令Encoding(variable)告诉我，有一个未知的混合物。和UTF-8编码。以上所有都编码为UTF-8。
此代码复制了我的mac上的问题：
library(foreign)
vec<-c('sécurité', 'service à la clientèle', 'assembleur', 'labour')
write.csv(data.frame(vec), file='~/Desktop/test.csv')
我对write_excel_csv()做了同样的尝试，得到了相同的结果。
我只能假设这是utf-8编码的某种问题，但我可以＆＃39;我看到了解决这个问题的方法。
谢谢。
