You open the HTML5 Project Properties dialog box by right-clicking any HTML5 project node in the Projects window and choosing Properties. The Sources page lets you set the locations for the site root and the folder for tests.
You can modify the following properties in the Sources page of the dialog box.
The project character encoding determines how the IDE interprets characters in your source files. The IDE displays and saves any new files you create using the encoding set by the project in which they reside. The default character encoding used with projects is UTF-8. Use the Encoding drop-down to change the character encoding used with the project.
For more information on Project encoding, see About Project Encodings.
