+// email: yueheng.xu@intel.com

+// Intel Corporation, Oregon, USA
+// Last Update: September 7, 1999
+// Revision History: 
+// 09/07/1999 - initial version.
+// 09/28/1999 - changed leftbyte and rightbyte from char to unsigned char 
+//              in struct DByte
+// 04/10/1999 - changed leftbyte. rightbyte to uint8_t in struct DByte;
+//              added table UnicodeToGBKTable[0x5200]
+//            
+// 05/16/2000 - added gUnicodeToGBKTableInitialized flag for optimization
+// ======================================================================================
+// Table GBKToUnicode[] maps the GBK code to its unicode.
+// The mapping data of this GBK table is obtained from 
+// ftp://ftp.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP936.TXT
+// Frank Tang of Netscape wrote the original perl tool to re-align the 
+// mapping data into an 8-item per line format ( i.e. file cp936map.txt ).
+//
+// The valid GBK charset range: left byte is [0x81, 0xfe], right byte are
+// [0x40, 0x7e] and [0x80, 0xfe]. But for the convenience of index 
+// calculation, the table here has a single consecutive range of 
+// [0x40, 0xfe] for the right byte. Those invalid chars whose right byte 
+// is 0x7f will be mapped to undefined unicode 0xFFFF.
+//
+// 
+// Table UnicodeToGBK[] maps the unicode to GBK code. To reduce memory usage, we
+// only do Unicode to GBK table mapping for unicode between 0x4E00 and 0xA000; 
+// Others let converter to do search from table GBKToUnicode[]. If we want further
+// trade memory for performance, we can let more unicode to do table mapping to get
+// its GBK instead of searching table GBKToUnicode[].
