title: Read huge dataset with R and UTF-8 encoding?
body: <p>I'm using RStudio and I have a huge data set (30m rows x 5 cols; numbers and text) in .csv format. When I try to import that Dataset, it is "impossible" to read it with <code>read.csv</code>, so I installed <code>library(sqldf)</code>. With the command <code>read.csv.sql</code> I'm able to open my dataset, which takes ~45 minutes. <code>sqlddf</code> package can read it, but doesn't have the read.csv option <code>fileEncoding = 'UTF-8'</code>, so when I read that file a lot of Unicode characters are wrong, such a Spanish words like "Camión" or "España".</p>
  
  <p>Does anyone knows about the right library or command that allows me to import that huge Dataset with UTF-8 encoding? </p>
