How to display the ascii characters in java using unix OS

The below code is not able to converting the Hexa decimal characters into Ascii characers in Unix.
byte[] bytes = newbyte[hex.length()/2];

for(int i=0;i<bytes.length;i++){
bytes[i] = (byte)Integer.parseInt(hex.substring(2*i, 2*i+2),16);
String multi = new String(bytes);
System.out.println(" multi value from unHex method "+multi);

The above code when i run in Windows, displaying +j, but in unix dispalying different characters.

Do i need to set any characterset before converting the hexa into Ascii. Please guide me what i have to do.

Lower ASCII characters.

Hi, I'm writing a BBS telnet program. I'm having issues with it not displaying lower ASCII characters. For example, instead of displaying the "smiley face" character (Ctrl-B), it displays ^B. Is this because i'm using Ncurses? If so, is there any way around this? Thanks. (3 Replies)

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
