Mainframe iconv Converters for Japanese Characters
Mainframe iconv converters between ShiftJIS/eucJP/UCS2 and
NEC-JIPS/Hitachi-KEIS/Fujitsu-JEF were introduced at HP-UX 11i v1. This release
includes several fixes of mapping errors for JIS standard characters.
Summary of Change
This release of mainframe iconv conversion tables includes numerous fixes for mapping
errors for JIS standard characters in the basic parts of those mainframe codesets. The
detailed changes are described in MFConvChanges.jips, MFConvChanges.keis, and
MFConvChanges.jef under the /usr/share/doc directory.
In addition, this release of mainframe iconv conversion methods includes a fix to handle
an incomplete shift sequence at the end of an input buffer.
Impact
If you have already used the HP-UX 11i v1 version of mainframe iconv converters and
then use this version, the results will be different because of fixes in mapping for JIS
standard characters. Therefore, HP recommends that you save the previously installed
tables and rename them prior to installation of this release. You can then convert
persistent data back using the old tables and then reconvert it using the new tables to
achieve the correct representation.
If the last character in the input buffer could be a valid character OR an incomplete shift
sequence, iconv returns EINVAL. If that character is the final one of the input file, iconv
will not return successfully without appending other dummy data like NULL to that
character. That character is 0x1a for jipsj, 0x3f for jipsec/jipsek and 0xa for
keis7c/keis7k/keis8c/keis8k, which could be a control character OR an incomplete
shift sequence.
Compatibility
No compatibility problems are anticipated. However, if compatibility concerns arise with
regard to persistent data stored on an older HP-UX system, HP recommends that you
save the previously installed tables and rename them prior to installation of this release.
You can then convert the persistent data back using these old tables and then reconvert
the data to the correct representation using the new iconv tables.
Performance
No performance issues.
