Configuring for multi-byte characters
To represent non-English languages on a screen, UTF-8 Unicode encoding is required.
The character encoding for Western European languages is ISO-8859-1 (this encoding is usually the default character coding for most applications). You must configure both the application and the database to support Unicode and the character encoding schemas.
In WFM 5.0 and later releases, UTF-8 is the default encoding for the Oracle database.
