big5 - A character encoding system (codeset) for Traditional Chinese DESCRIPTION
The big5 codeset is one of several codesets that support the Traditional Chinese language. This codeset includes the following character sets: ASCII Big-5 The big5 codeset uses a combination of single-byte data and two-byte data to represent ASCII characters, symbols, and Chinese ideographic characters. ASCII Characters All ASCII characters are represented in the form of single-byte, 7-bit data in the big5 codeset; that is, the most significant bit (MSB) of a byte that represents an ASCII character is always set off. For more information, see ascii(5). Big-5 Character Groups The Big-5 character set defines the following character groups: Special symbols (408) Level 1 characters (5401) Level 2 characters (7652) Level 1 user-defined space (785) Level 2 user-defined space (2983) Level 3 user-defined space (2041) Code Values for Big-5 Characters Each Big-5 character is represented by a two-byte code that compiles according to the Big-5 standard. The MSB of the first byte is always set on while that of the second byte can be on or off. Code ranges for characters in the different character groups are as follows: Special symbols: A140 to A3BF Level 1 characters: A440 to C67E Level 2 characters: C940 to F9D5 Level 1 user-defined space: FA40 to FEFE Level 2 user-defined space: 8E40 to A0FE Level 3 user-defined space: 8140 to 8DFE In this space, the valid code range for the first byte is 81 to FE, while that for the second byte is 40 to 7E and A1 to FE. Codeset Conversion The following codeset converter pairs are available for converting Traditional Chinese characters between big5 and other encoding formats. Refer to iconv_intro(5) for an introduction to codeset conversion. For more information about the other codeset for which big5 is the input or output, see the reference page specified in the list item. dechanyu_big5, big5_dechanyu Converting from and to DEC Hanyu: dechanyu(5) dechanzi_big5, big5_dechanzi Converting from and to DEC Hanzi: dechanzi(5) eucTW_big5, big5_eucTW Converting from and to Taiwanese Extended UNIX Code: eucTW(5) sbig5_big5, big5_sbig5 Converting from and to Shift Big-5: sbig5(5) telecode_big5, big5_telecode Converting from and to Telecode: telecode(5) UCS-2_big5, big5_UCS-2 Converting from and to UCS-2: Unicode(5) UCS-4_big5, big5_UCS-4 Converting from and to UCS-4: Unicode(5) UTF-8_big5, big5_UTF-8 Converting from and to UTF-8: Unicode(5) Note The big5 encoding format is identical to the encoding format used in PC code pages that support Traditional Chinese. Therefore, you can use codeset converters that convert between big5 and UCS-2, UCS-4, or UTF-8 to convert Traditional Chinese data between PC code-page and Uni- code encoding formats. Refer to code_page(5) for a discussion of how the operating system supports PC code pages. Fonts for Big-5 Characters The operating system supports Big-5 code by internally converting characters to DEC Hanyu. Therefore, DEC Hanyu fonts are used for Big-5 characters. Both display and printer fonts are provided for DEC Hanyu and these are listed in the dechanyu(5) reference page. For general information about printer support for and codeset conversion of Asian text, refer to i18n_printing(5). SEE ALSO

deckorean - A character encoding system (codeset) for Korean DESCRIPTION
The DEC Korean (deckorean) codeset consists of the following character sets: ASCII KSC 5601-1987 For the symbols and ideographic characters defined in the KSC 5601-1987 character set, DEC Korean uses 2-byte data representation. For ASCII characters, DEC Korean uses single-byte 7-bit data representation; that is, the most significant bit (MSB) of the byte that repre- sents an ASCII character value is always set off. For more information on the ASCII character set, refer to ascii(5). KSC 5601-1987 Characters KSC 5601-1987 is a national standard that defines a primary set of graphic characters for Korean information interchange. The standard defines a character set with a total of 8224 characters that are arranged in a code table. The code table has 94 rows, numbered from 1 to 94. Each row has 94 columns, also numbered from 1 to 94. Different kinds of characters occupy different areas of the code table as follows: Special characters: 986 graphic symbols that reside in rows 1 to 12 Hangul characters: 2350 Korean (Hangul) characters that reside in rows 16 to 40 Hanja characters: 4888 Chinese characters that reside in rows 42 to 93 DEC Korean Encoding Values To differentiate KSC 5601-1987 codes from ASCII codes, the most significant bit (MSB) of both the first and the second byte of a KSC 5601 character value is always set on. The value of a KSC 5601 character can be determined from its row and column number as follows: 1st byte = A0 + Row number 2nd byte = A0 + Column number For example, if a character is positioned at the first column of the 36th row, its value is CA41, which is calulated as follows: 1st byte = A0(hex) + 36 = C4 (hex) 2nd byte = A0(hex) + 01 = A1 (hex) Codeset Conversion The following codeset converter pairs are available for converting Korean characters between deckorean and other encoding formats. Refer to iconv_intro(5) for an introduction to codeset conversion. For more information about the other codeset for which deckorean is the input or output, see the reference page specified in the list item. eucKR_deckorean, deckorean_eucKR Converting from and to Korean Extended UNIX Code: eucKR(5). UCS-2_deckorean, deckorean_UCS-2 Converting from and to UCS-2 format: Unicode(5). UCS-4_deckorean, deckorean_UCS-4 Converting from and to UCS-4 format: Unicode(5). UTF-8_deckorean, deckorean_UTF-8 Converting from and to UTF-8 format: Unicode(5). There are also codeset converters that convert between the Microsoft Korean code-page format (cp949) used on PC systems and UCS-2, UCS-4, and UTF-8 formats. Note that if the UCS-2, UCS-4, or UTF-8 output from these converters is then converted to DEC Korean, some Hangul char- acters may be lost. For more information, see code_page(5). DEC Korean Fonts The operating system provides Korean fonts for both screen display and printers. The following bitmap fonts are available in various sizes and typefaces for 75dpi and 100dpi display devices: Fonts in Gotic Family: -adecw-gotic-medium-r-normal--16-160-75-75-m-160-ksc5601.1987-1 -adecw-gotic-medium-r-normal--24-240-75-75-m-240-ksc5601.1987-1 -adecw-gotic-medium-r-normal--16-160-100-100-m-160-ksc5601.1987-1 -adecw-gotic-medium-r-normal--24-240-100-100-m-240-ksc5601.1987-1 Fonts in Myungcho Family: -adecw-myungcho-medium-r-normal--16-160-75-75-m-160-ksc5601.1987-1 -adecw-myungcho-medium-r-nor- mal--32-320-75-75-m-320-ksc5601.1987-1 -adecw-myungcho-medium-r-normal--24-240-75-75-m-240-ksc5601.1987-1 -adecw-myungcho-medium-r- normal--16-160-100-100-m-160-ksc5601.1987-1 -adecw-myungcho-medium-r-normal--24-240-100-100-m-240-ksc5601.1987-1 -adecw-myungcho- medium-r-normal--32-320-100-100-m-320-ksc5601.1987-1 Fonts in Screen Family: -adecw-screen-medium-r-normal--18-180-75-75-m-160-ksc5601.1987-1 -adecw-screen-medium-r-normal--24-240-75-75-m-240-ksc5601.1987-1 -adecw-screen-medium-r-normal--18-180-100-100-m-160-ksc5601.1987-1 -adecw-screen-medium-r-nor- mal--24-240-100-100-m-240-ksc5601.1987-1 -adecw-screen-medium-r-normal--18-180-100-100-m-160-ksc5601.1987-1 -adecw-screen-medium-r- normal--24-240-100-100-m-240-ksc5601.1987-1 For PostScript printers, the operating system provides only Munjo fonts.
