title: Greek alphabet being converted to unicode in dataframe? any packages to support use of different alphabets?
body: <p>I created a column containing Greek words, e.g:</p>
  <p><code>vocab&lt;-c(&quot;να&quot;, &quot;το&quot;,&quot;δεν&quot;, &quot;είναι&quot;)</code>
  however, when shown in a data frame these words are shown as:</p>
  <p>&quot;㯚, tο, deν, eί㯚ι &quot; respectivley.</p>
  <p>Are there any packages that help R cope with the use of foreign alphabets and treat them the same as they would the standard English one? I don't really understand why they don't automatically treat these symbols as normal English letters.</p>
  <p>Thanks for your help!</p>
