If the actual character set that describes the characters in a data source's files is different from the character set Relativity has recorded, the Character Set Maintenance dialog box can be used to change it.
The Character Sets tab opens, displaying a list of character sets already in the catalog.
The Modify FD character sets section is displayed.
A list of files currently using that character set are listed.
By default, in the File Definition list, all files are selected to replace the old character set with the new one.
The changes are saved.
To quickly change the character set of a particular FD file, select the required entry in the Catalog Explorer, then update the Source Character Set and Native Character Set properties in the Properties pane.
