The encoding of text in character-based fields
Data in CHAR, VARCHAR, and other text-based fields have a specific character encoding. When databases are created, they can specify the encoding that will be used throughout the database.
Campaign can be configured to use one of many different character encodings on a database-wide scale. Per-column encodings are not supported.
In many databases, the database client transcodes between the encoding of the database and the encoding that an application uses. This is common when an application uses some form of Unicode but the database uses a language-specific encoding.
