Question

As CP037 encoding is not supported by BlackBerry by default does anyone know if there is any ready made libaray that I would be able to use? I’ve had a look online and I can’t seem to see anything. Is the only option to write one myself? Does anyone have any tips on how to do such a thing?

Answer 1

Writing your own bytes -> String decoder seems pretty straightforward, as the encoding has no more than 256 characters. Just turn the table from Wikipedia into a switch statement, and accumulate the resulting characters into a String.

byte[] rawCP037data = getEbcdicDatabytes();
StringBuffer buf = new StringBuffer();
for(int i = 0; i < rawCP037data.length; i++) {
    buf.append(convertCP037toUnicodeChar(rawCP037data[i]));
}
String decodedString = buf.toString();

char convertCP037toChar(byte b) {
    switch (b) {
    case 0x99:
      return 'r';
    case 0xAB:  // upside down question mark
      return 0x00BF;
    // TODO! fill out the rest of the table here
    }
}
