DDS for physical and logical files


Appendix A. Unicode considerations for database files

This appendix describes Unicode considerations for the positional entries and keyword entries for database (physical and logical) files.

Unicode is a universal encoding scheme for written characters and text that enables the exchange of data internationally. A Unicode field can contain all types of characters used on an iSeries(TM) server, including ideographic (DBCS). Unicode data is composed of code units, which represent the minimal byte combination that can represent a unit of text.

There are three transformation formats (encoding forms) of Unicode that are supported with physical and logical file DDS:

In the following topics, references to UTF-16 imply UCS-2 as well.

Positional and keyword entry considerations for database files that use Unicode:

The following topics describe how to specify DDS position 30 through 37 and position 45 through 80 for describing database files. Positions not mentioned have no special considerations for Unicode.
