Appendix C. Double-Byte Character Set (DBCS) Support

A Double-Byte Character Set supports languages that have more characters than can be represented by 8 bits (such as Korean Hangeul and Japanese kanji). REXX has a full range of DBCS functions and handling techniques.

These include:

Note:
The use of DBCS does not affect the meaning of the built-in functions as described in Functions. This explains how the characters in a result are obtained from the characters of the arguments by such actions as selecting, concatenating, and padding. The appendix describes how the resulting characters are represented as bytes. This internal representation is not usually seen if the results are printed. It may be seen if the results are displayed on certain terminals.
