The Character Code Conversion Routines For HKSCS-2004 download contains two functions for converting legacy encodings - Big5, or Unicode with Private Use Area (PUA) – to Unicode 4.1.
The Microsoft Character Code Conversion Routines for HKSCS-2004 contains two conversion/trans-coding functions. Use the functions to write applications to transform, trans-code, and migrate HKSCS character data encoded with old encodings to character data with new Unicode 4.1 encodings.
The Hong Kong Character Set (HKCS) includes:
• The Big5 Character Set (as defined in Microsoft Code Page 950)
• The Hong Kong Supplementary Character Set (HKSCS)
Historically, HKCS characters were encoded in one of two ways:
• Unicode / ISO 10646 encoding
• Big5 encoding
Over time, the HKSCS character set (character repertoire) expanded, and the Unicode code point assignments for many HKSCS characters changed. Several years ago, most HKSCS characters were encoded with Unicode Private Use Area (PUA) assignments. PUA code points are very problematic for information processing and database systems. In May 2005, HKSCS-2004 was released to the public by the Government of Hong Kong S.A.R. All of the HKSCS-2004 characters have Unicode 4.1, non-PUA code point assignments.
Windows XP and later internally process all characters as Unicode data. All new HKSCS-2004 documents and data records will be created in Windows using Unicode 4.1, non-PUA code point assignments.
HKSCS-2004 and beyond will be supported in Windows in Unicode-encoding only. Two types of legacy-compatibility issues result:
• Conversion of legacy Unicode-encoded HKSCS documents and data to Unicode 4.1
• Conversion of Big5-encoded HKSCS documents and data to Unicode 4.1
Legacy Unicode-encoded HKSCS documents and data records must be converted to Unicode 4.1 in order to remove the PUA code points. Secondly, most Big5-encoded HKSCS documents and data records will need to be converted to Unicode 4.1 to work properly on Windows and to take advantage of new characters provided in HKSCS-2004.
Supported Operating System
Longhorn (Windows Code Name), Windows 2000 Service Pack 4, Windows Server 2003 Service Pack 1, Windows XP, Windows XP Professional Edition
The functions are built for 32-bit platforms.
The Microsoft Character Code Conversion Routines for HKSCS-2004 requires Visual Studio® .NET, or later in order to use the starter code for sample applications that is included, and to integrate, link and build the functions with new applications.
