title: Oracle SQL Developer environment encoding
body: <p>I have Oracle SQL Developer (3.1.07) and I'm trying to work with a database that uses <code>WE8ISO8859P1</code> encoding:</p>
  
  <pre><code>SELECT * FROM nls_database_parameters WHERE parameter = 'NLS_CHARACTERSET';
  </code></pre>
  
  <p>I have problems with saving packages that contains unicode symbols. When I open previously saved package all unicode symbols are turned to <code>'¿'</code>.</p>
  
  <p>What settings do I have to change to make SQL Developer keep those symbols?
  I've tried to set environment encoding to <code>'ISO-8859-15'</code> and some other encodings, but it won't help.</p>
