EBCDIC Conversion in groovy

[Nishiru San]

I was trying for ASCII to EBCDIC conversion in groovy

I was trying to write hex value 81 and 82 ( which are EBCDIC hex values for a and b) to a file.

Please find the code below

byte s = (byte)0x81
byte s1 =(byte)0x82
f=new File("D:/sd")
s2= new String(s) + new String(s1)
f.write(new String(s2))    

But the code writes hex value 3F and 82 to the file. It seems that when i give byte(0x81) it is not resolving and putting 3F which means character '?' in ASCII. All other hex values are fine.

I have tried this in Windows 7 32 bit machine. Tried the same code in Oracle Enterprise 5 Linux 64 bit machine. Surprisingly the same code wrote 'EFBF EFBF' in the file .

Can someone advice on this.

Instead of f.write used f.setBytes to solve the issue
