body: <p>Hı all. Thank you for this community. I want use odoo for my job. but I'm so tired, I'm on the verge of giving up from odoo.</p>
  
  <p>I would be very grateful if you help.</p>
  
  <p>After installation, I can get once localhost8069 . And creating database.
   ANd ı take create database error.</p>
  
  <p>Database creation error: "invalid byte sequence for encoding "UTF8": 0xff " while parsing /usr/lib/python2.7/dist-packages/openerp/addons/base/base_data.xml:55, near     &lt;span&gt;--&lt;br/&gt; Administrator&lt;/span&gt; </p>
  
  <p>After this error  ı take always 500 internal server error. I can not see login interface anymore.  I just see 500 internal server error.</p>
  
  <p>6 days I'm working and I could not reach a solution. I used ubuntu and pardus ( some kind debian) . And the results did not change.</p>
  
  <p>But when ı used w7 ı succeed. I was able to get odoo. But ı want use odoo in linux not windows.</p>
