RStudio - How to create a WordCloud with spanish characters like: à,è,ì,ò,ù,ñ - r

Question

I'm importing a txt file with words in spanish, because I want to create wordCloud...
The problem is that I get this words without accent marks inside my wordcloud...
There are words like: "México" that are displayed as "mc3a9xico" ???
text <- readLines(file.choose())
# Load the data as a corpus
docs <- Corpus(VectorSource(text))
# Convert the text to lower case
docs <- tm_map(docs, content_transformer(tolower))
# Remove numbers
docs <- tm_map(docs, removeNumbers)
# Remove english common stopwords
docs <- tm_map(docs, removeWords, stopwords("english"))
# Remove your own stop word
# specify your stopwords as a character vector
docs <- tm_map(docs, removeWords, c("blabla1", "blabla2"))
# Remove punctuations
docs <- tm_map(docs, removePunctuation)
# Eliminate extra white spaces
docs <- tm_map(docs, stripWhitespace)
# Text stemming
# docs <- tm_map(docs, stemDocument)
dtm <- TermDocumentMatrix(docs)
m <- as.matrix(dtm)
v <- sort(rowSums(m),decreasing=TRUE)
d <- data.frame(word = names(v),freq=v)
head(d, 10)
set.seed(1234)
#Generate WordCloud
wordcloud(words = d$word, freq = d$freq, min.freq = 1,
max.words=200, random.order=FALSE, rot.per=0.35,
colors=brewer.pal(8, "Dark2"))

The problem was that I didn't set my System Locale. So after trying several times to change to spanish, I was getting this error: "OS reports request to set locale to "sp_MX.UTF-8" cannot be honored" So I ended up using this:
Sys.setlocale(category = "LC_ALL", locale = "en_US.UTF-8")
And after that everything was working.
Thanks to #hrbrmstr He pointed me to the actual problem :)
