Mixed Codesets

PROIV supports mixed codesets in a single application, enabling the developer to transparently handle application display and data entry in one codeset, while processing and storing the incoming information in the same or a superset of the same codeset.

The originating codeset, or a superset of it, is required so that information is not lost during translation. For example, an application reads data from a file in Shift JIS format and processes it in UTF8 format, and then returns processing results in Shift JIS. If a character cannot be mapped from one codeset to another codeset, the character ‘?’ appears by default.

The following is an example of mixed codesets:

Display/Input Codeset	Processing Codeset	Storage Codeset
CODE1252	CODE0850	CODE0850
CODE1252	CODE0437	CODE0437
Shift JIS	UTF8	UTF8
Shift JIS	Shift JIS	EUC
ASCII	UTF8	UTF8
KSC	UTF8	UTF8
Unicode	UTF8	UTF8
BIG5	UTF8	UTF8
