Corrected Character Mappings to iconv(1) and
iconv(3C)
This release contains defect fixes for incorrect character mappings. The corrections
concern the Simplified Chinese, Traditional Chinese, Japanese, and Korean characters
of HP-UX.
Corrected character converter mappings allow for improved interoperability when
sending or receiving converted character data to/from Unicode-aware systems.
Correction for Simplified Chinese
A patch corrects an incorrect character mapping that occurs when converting between
hp15CN and Unicode (UCS2)/UTF-8 for Simplified Chinese.
Specifically, the Simplified Chinese character “Double Vertical Line” mapped incorrectly
when converting between hp15CN and UCS2/UTF-8. This character was being mapped
to the “Parallel To” character, which is a different character.
The following table summarizes the change applied to iconv tables:
The hp15CN=ucs2 and ucs2=hp15CN iconv converter tables are affected. 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 mapping:
Correction for Traditional Chinese
A patch corrects several incorrect character mappings that occur when converting
between Big-5/EUC and Unicode (UCS2)/UTF-8 for Traditional Chinese.
