I have a vector of raw text that includes English and French words, so there are French words that have accented characters like this:
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
The command Encoding(variable) tells me that there's a mix of 'unknown' and UTF-8 encodings. All of the ones above are coded as UTF-8.
This code replicates the problem on my mac:
library(foreign)
vec<-c('sécurité', 'service à la clientèle', 'assembleur', 'labour')
write.csv(data.frame(vec), file='~/Desktop/test.csv') 
I have tried the same with write_excel_csv() and I get the same results. 
I can only assume this is some kind of problem with the utf-8 encoding, but I can' t see my way to figure this out.
Thank you.
