 \subsection{\label{ref:CreateYourOwnWPS}Themes -- Create Your Own}
 The theme files are simple text files, and can be created (or edited) in your
 favourite text editor. To make sure non-English characters 
-display correctly in your WPS you must save the .wps file with UTF-8 character 
-encoding. This can be done in most editors, for example Notepad in Windows 2000
-or XP (but not in 9x/ME) can do this.
