In Unicode mode, the PowerCenter Integration Service recognizes multibyte character data and allocates up to two bytes for every character. The PowerCenter Integration Service performs code page conversions from sources to targets. When you set the PowerCenter Integration Service to Unicode data movement mode, it uses a Unicode character set to process characters in a specified code page, such as Shift-JIS or UTF-8.
When you run the PowerCenter Integration Service in Unicode mode, it enforces session code page relationships.
