25: /*
26: * BIG5-2003 is a slightly extended and slightly modified version of BIG5.
27: * It is actually nearer to Microsoft CP950 than to BIG5. The differences
28: * between EASTASIA/OTHER/BIG5.TXT found on ftp.unicode.org and BIG5-2003.TXT
29: * are as follows:
30: *
31: * 1. Some characters in the symbols area (0xA140..0xA2CE) are defined
32: * differently:
33: *
34: * code BIG5.TXT BIG5-2003.TXT
35: * 0xA145 0x2022 # BULLET 0x2027 # HYPHENATION POINT
36: * 0xA14E 0xFF64 # HALFWIDTH IDEOGRAPHIC COMMA
37: * 0xFE51 # SMALL IDEOGRAPHIC COMMA
38: * 0xA156 0x2013 # EN DASH 0x2015 # HORIZONTAL BAR
39: * 0xA15A --- 0x2574 # BOX DRAWINGS LIGHT LEFT
40: * 0xA1C3 --- 0xFFE3 # FULLWIDTH MACRON
41: * 0xA1C5 --- 0x02CD # MODIFIER LETTER LOW MACRON
42: * 0xA1E3 0x223C # TILDE OPERATOR 0xFF5E # FULLWIDTH TILDE
43: * 0xA1F2 0x2641 # EARTH 0x2295 # CIRCLED PLUS
44: * 0xA1F3 0x2609 # SUN 0x2299 # CIRCLED DOT OPERATOR
45: * 0xA1FE --- 0xFF0F # FULLWIDTH SOLIDUS
46: * 0xA240 --- 0xFF3C # FULLWIDTH REVERSE SOLIDUS
47: * 0xA241 0xFF0F # FULLWIDTH SOLIDUS 0x2215 # DIVISION SLASH
48: * 0xA242 0xFF3C # FULLWIDTH REVERSE SOLIDUS
49: * 0xFE68 # SMALL REVERSE SOLIDUS
50: * 0xA244 0x00A5 # YEN SIGN 0xFFE5 # FULLWIDTH YEN SIGN
51: * 0xA246 0x00A2 # CENT SIGN 0xFFE0 # FULLWIDTH CENT SIGN
52: * 0xA247 0x00A3 # POUND SIGN 0xFFE1 # FULLWIDTH POUND SIGN
53: * 0xA2A4 0x2550 # BOX DRAWINGS DOUBLE HORIZONTAL
54: * 0x2501 # BOX DRAWINGS HEAVY HORIZONTAL
55: * 0xA2A5 0x255E # BOX DRAWINGS VERTICAL SINGLE AND RIGHT DOUBLE
56: * 0x251D # BOX DRAWINGS VERTICAL LIGHT AND RIGHT HEAVY
57: * 0xA2A6 0x256A # BOX DRAWINGS VERTICAL SINGLE AND HORIZONTAL DOUBLE
58: * 0x253F # BOX DRAWINGS VERTICAL LIGHT AND HORIZONTAL HEAVY
59: * 0xA2A7 0x2561 # BOX DRAWINGS VERTICAL SINGLE AND LEFT DOUBLE
60: * 0x2525 # BOX DRAWINGS VERTICAL LIGHT AND LEFT HEAVY
61: * 0xA2CC --- 0x3038 # HANGZHOU NUMERAL TEN
62: * 0xA2CD 0x5344 0x3039 # HANGZHOU NUMERAL TWENTY
63: * 0xA2CE --- 0x303A # HANGZHOU NUMERAL THIRTY
64: *
65: * 2. A control symbols area is added:
66: *
67: * code
68: * 0xA3C0..0xA3E0 U+2400..U+2421
69: *
70: * 3. The Euro sign is added:
71: *
72: * code
73: * 0xA3E1 0x20AC # EURO SIGN
74: *
75: * 4. Some characters in the main area are defined differently:
76: *
77: * code BIG5.TXT BIG5-2003.TXT
78: * 0xC255 0x5F5D 0x5F5E
79: *
80: * 5. The area 0xC6A1..0xC7FE is organized differently:
81: *
82: * code
83: * 0xC6A1..0xC6BE numerals (was in BIG5.TXT at 0xC7E9..0xC7FC)
84: * 0xC6BF..0xC6D7 radicals
85: * 0xC6D8..0xC6E6 rarely used symbols
86: * 0xC6E7..0xC77A hiragana (U+3041..U+3093, was in BIG5.TXT at 0xC6A5..0xC6F7)
87: * 0xC77B..0xC7F2 katakana (U+30A1..U+30F6, was in BIG5.TXT at 0xC6F8..0xC7B0)
88: *
89: * 6. Some characters are added at 0xF9D6..0xF9DC.
90: *
91: * 7. Box drawing characters are added at 0xF9DD..0xF9FE.
92: *
93: * Note: 4 of these characters are mapped in a non-inversible way, because
94: * Unicode does not yet include the corresponding characters:
95: *
96: * code Unicode approximation
97: * 0xF9FA BOX DRAWINGS DOUBLE ARC DOWN AND RIGHT 0x2554
98: * 0xF9FB BOX DRAWINGS DOUBLE ARC DOWN AND LEFT 0x2557
99: * 0xF9FC BOX DRAWINGS DOUBLE ARC UP AND RIGHT 0x255A
100: * 0xF9FD BOX DRAWINGS DOUBLE ARC UP AND LEFT 0x255D
101: *
102: * 8. Private area mappings are added:
103: *
104: * code Unicode
105: * 0x{81..8D}{40..7E,A1..FE} U+EEB8..U+F6B0
106: * 0x{8E..A0}{40..7E,A1..FE} U+E311..U+EEB7
107: * 0x{FA..FE}{40..7E,A1..FE} U+E000..U+E310
108: *
109: * These mappings are not contained in the BSMI Big5-2003 standard. However,
110: * they were contained in a draft of it.
