Pet peeve of the day

  Hi;
  
  I know that - I spent hours changing these in my code. But it would have been nice if J# supported all the encoding "names" that java does - it would save a number of people a lot of work. (In my case we have common source code and want our java to just compile.)
  
  thanks - dave

  Hi,
  
  As per program manager's input,
  
  ----------
  Here are the string mappings directly supported:
  
  // Mapped to: Unicode LittleEndian
  "Unicode"
  "UnicodeLittle"
  
  // Mapped to: Unicode BigEndian
  "UnicodeBig",
  
  // Mapped to: UTF8
  "UTF8",
  
  // Mapped to: UTF7
  "UTF7",
  
  // Mapped to: ASCII
  "ASCII",
  
  //Mapped to: Codepage 1252
  "8859_1",
  "ISO-8859-1",
  "ISO-Latin-1",
  "Cp1252",
  "latin1",
  
  //Mapped to: Big5
  "Big5",
  
  //Mapped to: GB2312
  "GB2312",
  
  //Mapped to: SJIS
  "SJIS",
  
  //Mapped to: iso-2022-jp
  "JIS",
  
  //Mapped to: ks_c_5601-1987
  "KSC5601",
  
  //Mapped to: default encoding
  "Default",
  "default",
  
  Note that for everything else you can directly provide the Codepage prefixed with "Cp".
  ----------
  
  Hope this helps you.

  Hi;
  
  Please try:
  
  

  OutputStreamWriter o = new OutputStreamWriter(new FileOutputStream("data.out"), "utf-8");

  OutputStreamWriter o = new OutputStreamWriter(new FileOutputStream("data.out"), "windows-1252");

  String str = new String(new byte[4], "Shift_JIS");
  
  Work in java, not J# (there are others). That's why it's frustrating, it's there but J# didn't map some names.
  
  thanks - dave

  Hi,
  

  This is what our Program Manager Pratap Lakshman has to say on this issue...
  
  -------------
  

  J# surfaces all of the encodings supported on .NET.
  To get the complete list of supported encodings refer http://msdn2.microsoft.com/en-us/library/86hf4sb8(en-US,VS.80).aspx

   

  Users familiar with the level of the libraries for which J# provides equivalent functionality can refer to these encodings using names like Unicode, UnicodeLittle, UnicodeBig, UTF7, UTF8, ASCII, 8859_1, ISO-8859-1, etc.
  You can also, instead, specify the codepage to use for encoding. The table at http://msdn2.microsoft.com/en-us/library/86hf4sb8(en-US,VS.80).aspx lists the encodings and their associated codepages. Specify the codepage by prefixing it with "Cp". This convention should be familiar to users of the level of the library for which J# provides equivalent functionality.

   

  J# Example:
  Consider OutputStreamWriter:
  The encodings can be passed to the OutputStreamWriter as a second parameter as follows:

  
  import java.io.*;

   

  public class writer
  {
    public static void main(String[] args) throws Exception
    {
      String[] encoding =
      {
  // familiar names
  "Unicode",
  "UnicodeLittle",
  "UnicodeBig",
  "UTF7",
  "UTF8",
  "ASCII",
  "8859_1",
  "ISO-8859-1",
  "ISO-Latin-1",

   

  // or use codepage number prefixed with "Cp". Refer table at:
  // (http://msdn2.microsoft.com/en-us/library/86hf4sb8(en-US,VS.80).aspx)
