This is a problem you can face while developing applications in Eclipse here is a solution for this problem.And also a bug reported for this problem here


Windows Menu –> Preferences –> General (expand it) –> Workspace (click on it).
Look for a box “Text File Encoding”. Default will be “Cp1252″.
Change radio to select other and select “UTF-8″ from combo box.
