Options (Text Editor - File Extension Page)
Use the Options dialog box to specify how all files with certain file extensions are handled by SQL Server Management Studio. For each extension that you enter, you can select an editor. Thus, you can choose the SQL Server Management Studio editor in which documents of a certain type will open. To open the file extension options, click Options on the Tools menu, expand Text Editor, and then click File Extension.
When you select, from the Editor drop-down list, an option "with Encoding", a dialog box appears whenever you open a document of that type that allows you to select an encoding scheme for that document. This can be helpful if you are preparing versions of your scripts for use on a different operating system or in different target languages.
