Answer 1

I had the same problem in my mac, solved via below solution.

raw_data <- read.csv(file.choose(), stringsAsFactors = F,  encoding="UTF-8")

raw_data$textCol<- iconv(raw_data$textCol, "ASCII", "UTF-8", sub="byte")

data_corpus <- VCorpus(VectorSource(raw_data$textCol))

corpus_clean = tm_map(data_corpus, function(x) iconv(x, to='UTF-8-MAC', sub='byte'))

corpus_clean <- tm_map(data_corpus, content_transformer(tolower))
