/*
|
|
* BIG5-2003 is a slightly extended and slightly modified version of BIG5.
|
|
* It is actually nearer to Microsoft CP950 than to BIG5. The differences
|
|
* between EASTASIA/OTHER/BIG5.TXT found on ftp.unicode.org and BIG5-2003.TXT
|
|
* are as follows:
|
|
*
|
|
* 1. Some characters in the symbols area (0xA140..0xA2CE) are defined
|
|
* differently:
|
|
*
|
|
* code BIG5.TXT BIG5-2003.TXT
|
|
* 0xA145 0x2022 # BULLET 0x2027 # HYPHENATION POINT
|
|
* 0xA14E 0xFF64 # HALFWIDTH IDEOGRAPHIC COMMA
|
|
* 0xFE51 # SMALL IDEOGRAPHIC COMMA
|
|
* 0xA156 0x2013 # EN DASH 0x2015 # HORIZONTAL BAR
|
|
* 0xA15A --- 0x2574 # BOX DRAWINGS LIGHT LEFT
|
|
* 0xA1C3 --- 0xFFE3 # FULLWIDTH MACRON
|
|
* 0xA1C5 --- 0x02CD # MODIFIER LETTER LOW MACRON
|
|
* 0xA1E3 0x223C # TILDE OPERATOR 0xFF5E # FULLWIDTH TILDE
|
|
* 0xA1F2 0x2641 # EARTH 0x2295 # CIRCLED PLUS
|
|
* 0xA1F3 0x2609 # SUN 0x2299 # CIRCLED DOT OPERATOR
|
|
* 0xA1FE --- 0xFF0F # FULLWIDTH SOLIDUS
|
|
* 0xA240 --- 0xFF3C # FULLWIDTH REVERSE SOLIDUS
|
|
* 0xA241 0xFF0F # FULLWIDTH SOLIDUS 0x2215 # DIVISION SLASH
|
|
* 0xA242 0xFF3C # FULLWIDTH REVERSE SOLIDUS
|
|
* 0xFE68 # SMALL REVERSE SOLIDUS
|
|
* 0xA244 0x00A5 # YEN SIGN 0xFFE5 # FULLWIDTH YEN SIGN
|
|
* 0xA246 0x00A2 # CENT SIGN 0xFFE0 # FULLWIDTH CENT SIGN
|
|
* 0xA247 0x00A3 # POUND SIGN 0xFFE1 # FULLWIDTH POUND SIGN
|
|
* 0xA2A4 0x2550 # BOX DRAWINGS DOUBLE HORIZONTAL
|
|
* 0x2501 # BOX DRAWINGS HEAVY HORIZONTAL
|
|
* 0xA2A5 0x255E # BOX DRAWINGS VERTICAL SINGLE AND RIGHT DOUBLE
|
|
* 0x251D # BOX DRAWINGS VERTICAL LIGHT AND RIGHT HEAVY
|
|
* 0xA2A6 0x256A # BOX DRAWINGS VERTICAL SINGLE AND HORIZONTAL DOUBLE
|
|
* 0x253F # BOX DRAWINGS VERTICAL LIGHT AND HORIZONTAL HEAVY
|
|
* 0xA2A7 0x2561 # BOX DRAWINGS VERTICAL SINGLE AND LEFT DOUBLE
|
|
* 0x2525 # BOX DRAWINGS VERTICAL LIGHT AND LEFT HEAVY
|
|
* 0xA2CC --- 0x3038 # HANGZHOU NUMERAL TEN
|
|
* 0xA2CD 0x5344 0x3039 # HANGZHOU NUMERAL TWENTY
|
|
* 0xA2CE --- 0x303A # HANGZHOU NUMERAL THIRTY
|
|
*
|
|
* 2. A control symbols area is added:
|
|
*
|
|
* code
|
|
* 0xA3C0..0xA3E0 U+2400..U+2421
|
|
*
|
|
* 3. The Euro sign is added:
|
|
*
|
|
* code
|
|
* 0xA3E1 0x20AC # EURO SIGN
|
|
*
|
|
* 4. Some characters in the main area are defined differently:
|
|
*
|
|
* code BIG5.TXT BIG5-2003.TXT
|
|
* 0xC255 0x5F5D 0x5F5E
|
|
*
|
|
* 5. The area 0xC6A1..0xC7FE is organized differently:
|
|
*
|
|
* code
|
|
* 0xC6A1..0xC6BE numerals (was in BIG5.TXT at 0xC7E9..0xC7FC)
|
|
* 0xC6BF..0xC6D7 radicals
|
|
* 0xC6D8..0xC6E6 rarely used symbols
|
|
* 0xC6E7..0xC77A hiragana (U+3041..U+3093, was in BIG5.TXT at 0xC6A5..0xC6F7)
|
|
* 0xC77B..0xC7F2 katakana (U+30A1..U+30F6, was in BIG5.TXT at 0xC6F8..0xC7B0)
|
|
*
|
|
* 6. Some characters are added at 0xF9D6..0xF9DC.
|
|
*
|
|
* 7. Box drawing characters are added at 0xF9DD..0xF9FE.
|
|
*
|
|
* Note: 4 of these characters are mapped in a non-inversible way, because
|
|
* Unicode does not yet include the corresponding characters:
|
|
*
|
|
* code Unicode approximation
|
|
* 0xF9FA BOX DRAWINGS DOUBLE ARC DOWN AND RIGHT 0x2554
|
|
* 0xF9FB BOX DRAWINGS DOUBLE ARC DOWN AND LEFT 0x2557
|
|
* 0xF9FC BOX DRAWINGS DOUBLE ARC UP AND RIGHT 0x255A
|
|
* 0xF9FD BOX DRAWINGS DOUBLE ARC UP AND LEFT 0x255D
|
|
*
|
|
* 8. Private area mappings are added:
|
|
*
|
|
* code Unicode
|
|
* 0x{81..8D}{40..7E,A1..FE} U+EEB8..U+F6B0
|
|
* 0x{8E..A0}{40..7E,A1..FE} U+E311..U+EEB7
|
|
* 0x{FA..FE}{40..7E,A1..FE} U+E000..U+E310
|
|
*
|
|
* These mappings are not contained in the BSMI Big5-2003 standard. However,
|
|
* they were contained in a draft of it.
