The _suffix variable is used for translations that map source characters to semantically different characters. They indicate the nature of the semantic transformation.
The translations perform minor, yet essential, semantic changes to the data, such as halfwidth/fullwidth conversions, and Space folding modification.
The _suffix variable also indicates the form of character data translated from UNICODE to the KANJI1 server character set in one of the four possible encodings, for example Unicode_TO_Kanji1_KanjiEBCDIC. For a list of the encodings, see _encoding.
This form of translation is also useful for migrating object names. For information, see Migration.
