title: Reading csv file with Japanese characters into R
body: <p>I am struggling to have R read in a csv file which has some of its columns in standard English characters, some numerical and some fields in Japanese characters.Here is how the data looks like:</p>
  
  <pre><code>category,desc,otherdesc,volume
  UPC - 31401 Age Itameabura,かどや製油　純白ごま油,OIL_OTHERS_SML_ECO,83.0
  UPC - 31401 Age Itameabura,オレインリッチ,OIL_OTHERS_MED,137.0
  UPC - 31401 Age Itameabura,ＴＶキャノーラ油,OIL_CANOLA_OTHERS_LRG,3026.0 
  </code></pre>
  
  <p>Keeping the R's language setting as English, the japanese characters are converted into some gibberish. When I change the language setting in R to Japanese, <code>Sys.setlocale("LC_CTYPE", "japanese")</code>, I see the file is not read in at all. R gives an error saying:</p>
  
  <p>Error in make.names(col.names, unique = TRUE) : 
    invalid multibyte string at 'ｻcategory'</p>
  
  <p>I have no clue what's wrong with my csv file or the header names. Can you guide me as to how can I go about reading this csv file into R so that everything is displayed just as they do in the csv file? </p>
  
  <p>Thanks!
