By default, each character set you create is placed in a default character partition. With all the character sets in the same partition, you can be sure that the attributes in one character set will not be in some other character set. To view the default character partition, you can use the Relationship Editor.
You should avoid editing the character partition. Editing the character partition can lead to problems because in doing so you might unintentionally end up having attributes in more than one character set.
