HP-UX 11i December 2004 Release Notes

Internationalization
Corrected Character Mappings to iconv(1) and iconv(3C)
Chapter 16
342
Affected iconv conversions are conversions between sjis and UCS2 or UTF-8 as well as
conversions between eucJP and UCS2 or UTF-8.
sjis=ucs2, ucs2=sjis, eucJP=ucs2 and ucs2=eucJP are the affected iconv conversion
tables. These tables are shared by both UCS2 and UTF-8 conversions.
No compatibility problems are anticipated. However, if compatibility concerns arise with
regard to persistent data stored either in Unicode (UCS2) or UTF-8 on an HP-UX
system, it is possible to generate a simple conversion script to search for each occurrence
of an incorrect value in either UCS2 or UTF-8 and convert it to the correct value, based
on the following mappings:
Correction for Korean
A patch provides a defect fix to address standards non-conformance for Korean Unicode
(UCS2)/UTF-8 character mappings.
The currently supplied Korean iconv converter tables do not conform to the Unicode 2.1
and ISO-10646 (with 1997 amendments) standards in addition to the Korean national
standard, KSC-5700. The current mappings are considered obsolete by all noted
standards organizations.
The enhancement provides a set of standards-conformant iconv converter tables for
converting between eucKR and Unicode/UTF-8. Specifically, the obsolete region of
0x3d2e - 0x4dff has been re-mapped to the 0xac00 - 0xd7ff region specified in Unicode 2.1
for Hangul.
Without this modification, it is impossible to share data with any other system which is
standards-conformant in adhering to the Unicode 2.1/ISO-10646/KSC-5700 standards.
Affected iconv conversions are any conversions between eucKR and UCS2 or UTF-8.
The iconv conversion tables affected by this modification are eucKR=ucs2 and
ucs2=eucKR. These tables are shared by both UCS2 and UTF-8 conversions.
No compatibility problems are anticipated. However, if compatibility concerns arise with
regard to persistent data stored either in Unicode (UCS2) or UTF-8 on an HP-UX
system, it is recommended that the previously installed ucs2=eucKR table be saved and
renamed prior to installation of this fix. Persistent data can then be converted back to
eucKR using this old table and then reconverted to the correct Unicode/UTF-8
representation.
