Administration Services Console displays the File Encoding dialog box when a file that is being saved or read from a client location does not contain an encoding indicator.
If the file is to be used with a non-Unicode-mode application or with a version of Essbase Server prior to Release 7.0, when you click OK, an encoding indicator is added to the file. Therefore, in this case, all you need do is click OK.
If the file is a non-Unicode-encoded text file, the encoding indicator is within the locale header record.
If the file is to be used with a Unicode-mode application, you define the encoding by performing one of the following actions:
Select the UTF-8 option. If the file is not UTF-8 encoded, the option is not displayed.
From the list of text encodings, select a non-Unicode text encoding. Select carefully; selecting the wrong encoding can cause data corruption.

For non-Unicode-mode applications, the correct locale is already selected; make no changes and click OK.
