The problem is fixed..
Fix :
There is a setting in the Domino Designer preferences for encoding.
File->Preferences->Then type Workspace in the search box.
Select the Workspace link in the left navigation. There is a section called "Text File Encoding". That setting has to be "Windows-1252"for the special characters to show correctly.
So Set this setting and Build your project as I had problem in the Java class.
All should be good after this
