// GB18030Encoding.cs
//
// Ported to managed code from c_gb18030.c and related gb18030 dll files
//
//
// Abstract:
//
// Managed implimentation of GB18030-2000 (code page 54936) ported from implimentation in c_g18030.dll
// If you find a bug here you should check there (in windows) as well and visa versa.
// This file contains functions to convert GB18030-2000 (code page 54936) into Unicode, and vice versa.
//
// Notes:
// GB18030-2000 (aka GBK2K) is designed to be mostly compatible with GBK (codepage 936),
// while supports the full range of Unicode code points (BMP + 16 supplementary planes).
//
// The structure for GB18030 is:
// * Single byte:
// 0x00 ~ 0x7f
// * Two-byte:
// 0x81 ~ 0xfe, 0x40 ~ 0x7e (leading byte, trailing byte)
// 0x81 ~ 0xfe, 0x80 ~ 0xfe (leading byte, trailing byte)
// * Four-byte:
// 0x81 ~ 0xfe, 0x30 ~ 0x39, 0x81 ~ 0xfe, 0x30 ~ 0x39.
// The surrogare pair will be encoded from 0x90, 0x30, 0x81, 0x30
//
// The BMP range is fully supported in GB18030 using 1-byte, 2-byte and 4-byte sequences.
// In valid 4-byte GB18030, there are two gaps that can not be mapped to Unicode characters.
// 0x84, 0x31, 0xa5, 0x30 (just after the GB18030 bytes for U+FFFF(*)) ~ 0x8f, 0x39, 0xfe, 0x39 (just before the first GB18030 bytes for U+D800,U+DC00)
// 0xe3, 0x32, 0x9a, 0x36 (just after the GB18030 bytes for U+DBFF U+DFFF(**)) ~ 0xfe, 0x39, 0xfe, 0x39
//
//
// Note1: U+FFFF = 0x84, 0x31, 0xa4, 0x39
// Note2: U+DBFF U+DFFF = 0xe3, 0x32, 0x9a, 0x35
//
// Tables used in GB18030Encoding:
//
// Our data is similar to the 936 Code Page, so we start from there to build our tables. We build the
// normal double byte mapUnicodeToBytes and mapBytesToUnicode tables by applying differences from 936.
// We also build a map4BytesToUnicode table and a mapUnicodeTo4BytesFlags
//
// * mapUnicodeTo4BytesFlags
// This is an array of bytes, so we have to do a / 8 and << %8 to check the appropriate bit (see Is4Byte())
// If the bit is set its true.
//
// true - If set/true this is a 4 byte code. The value in mapUnicodeToBytes will be the 4 byte offset
// false - If cleared/false this is a 1 or 2 byte code. The value in mapUnicodeToBytes will be the 2 bytes.
//
// * mapUnicodeToBytes
// Contains either the 2 byte value of double byte GB18030 or the 4 byte offset for 4 byte GB18030,
// depending on the value of the flag in mapUnicodeTo4BytesFlags
//
// * mapBytesToUnicode
// mapBytesToUnicode maps 2 byte GB 18030 to Unicode like other DBCS code pages.
//
// * map4BytesToUnicode
// map4BytesToUnicode is indexed by the 4 byte offset and contains the unicode value for each 4 byte offset
//
//
// 4 Byte sequences
// We generally use the offset for the 4 byte sequence, such as:
//
// The index value is the offset of the 4-byte GB18030.
//
// 4-byte GB18030 Index value
// ============== ===========
// 81,30,81,30 0
// 81,30,81,31 1
// 81,30,81,32 2
// ... ...
//
// The value of map4BytesToUnicode cotains the Unicode codepoint for the offset of the
// corresponding 4-byte GB18030.
//
// E.g. map4BytesToUnicode[0] = 0x0080. This means that GB18030 0x81, 0x30, 0x81, 0x30 will be converted to Unicode U+0800.
//
// 4 Byte Surrogate Sequences
// Those work similarly to the normal 4 byte sequences, but start at a different offset
//
// We don't override IsAlwaysNormalized because GB18030 covers all of the unicode space, so isn't guaranteed to be normal.
//
