Well 129 == -63 if you coerce it to a byte. I assume that's the cause
of your problem, although I'm struggling to see where this is occuring.

I'm currently trying to sort out a problem with my implementation of
the MimeUtility class in the javamail specs. For the
encodeWord()/decodeWord() methods, my encoding encodes to the same
value as the Sun implementation, but the decoding is driving me
nuts. I'm able to successfully decode this into what should be the
correct byte[] array, but when used to instantiate the String value,
I'm getting a bogus character value.
Playing around with this, I've discovered that the problem seems to
be occurring with the String constructor, and can be demonstrated
without using the javamail code at all. Here is a little snippet
that shows the problem:
String longString = "Yada, yada\u0081";
try {
byte[] bytes = longString.getBytes("Cp1252"); //
get the bytes using CP1252
String newString = new String(bytes, 0, bytes.length,
"Cp1252"); // create a new string item using the same code page.
// last char of original is int 129, last char of
rebuilt string is int 63. System.out.println(">>>>>
original string = " + longString + " rebuilt string = " + newString);
System.out.println(">>>>> original string = " +
(int)longString.charAt(longString.length() - 1) + " rebuilt string
= " + (int)newString.charAt(longString.length() - 1));
} catch (Exception e) {
}
63 is the last value in the byte array after the getBytes() call,
and the Sun impl of MimeUtility.encodeWord() returns the string
"=?Cp1252?Q?Yada,_yada=3F?=" (0x3F == 63), so the correct value is
getting extracted. I'm at a loss to figure out why the round trip
coded above is corrupting the data. What am I missing here?
