title: read csv +unicode in R
body: <p>I have the same problem as explain in <a href="https://stackoverflow.com/questions/16838613/cannot-read-unicode-csv-into-r">here</a> ,the only difference is that the CSV file contain  non_english string and I couldn't find any solution for it : 
  when I read the csv file with out encoding it gives me no error but the data changed to :</p>
  
  <pre><code>network=read.csv("graph1.csv",header=TRUE)
  
    Ø§Ø´Ù¾ÛŒÙ„(60*4)
  </code></pre>
  
  <p>and if I run the <code>read.csv</code> with <code>fileEncoding</code> it gives me this error:</p>
  
  <pre><code> network=read.csv("graph1.csv",fileEncoding="UTF-8",header=TRUE)
  Warning messages:
  1: In read.table(file = file, header = header, sep = sep, quote = quote,  :
    invalid input found on input connection 'graph1.csv'
  2: In read.table(file = file, header = header, sep = sep, quote = quote,  :
    incomplete final line found by readTableHeader on 'graph1.csv'
