If you look closely, you will see that this is _not:_ the default character
encoding. This actually what *really* is sent over the wire.
Of course I can see the advantage of a full hex dump, but this would more be
an addition to the functionality, but my fix would be more like a bug-fix.
To demonstrate I have made a small code snipplet derived from the Wire.java.
This code should be runnable and print out the log: :
--------------
public class EncodingTest {
public static void main(String[] args) throws IOException {
// Setup:
byte[] b = new byte[]{(byte) 0xc3, (byte) 0xa6, (byte) 0xc3, (byte)
0xb8,
(byte) 0xc3, (byte) 0xa5};
ByteArrayInputStream instream = new ByteArrayInputStream(b);
//------
// ------ Old code: -------
// Reader reader = null;
// try {
// reader = new InputStreamReader(instream, "US-ASCII");
// } catch (UnsupportedEncodingException e) {
// reader = new InputStreamReader(instream);
// }
// ------------------------
StringBuffer buffer = new StringBuffer();
int ch;
// ------ Old code: -------
// while ((ch = reader.read()) != -1) {
// ------ Old code: -------
// ------ New code: -------
while ((ch = instream.read()) != -1) {
// ------------------------
if (ch == 13) {
buffer.append("[\\r]");
} else if (ch == 10) {
buffer.append("[\\n]\"");
buffer.insert(0, "\"");
System.out.println(buffer.toString());
buffer.setLength(0);
} else if ((ch < 32) || (ch > 127)) {
buffer.append("[0x");
buffer.append(Integer.toHexString(ch));
buffer.append("]");
} else {
buffer.append((char) ch);
}
}
if (buffer.length() > 0) {
buffer.append("\"");
buffer.insert(0, "\"");
System.out.println(buffer.toString());
}
}
}

I think, just using the default platform encoding is as bad as using
US-ASCII because it does not reflect was is *really* sent over the wire.
Actually the wirelog should ideally provide all bytes in hexadecimal
representation along with their supposed interpretation as characters in
some encoding (such as default platform encoding). A presentation
similar to hexdumps would me nice IMHO. However this might imply a small
buffering (16 bytes per line) to make a nice layout.
Sample output (hex values do not match text):
DE AD BE EF DE AD BE EF DE AD BE EF DE AD BE EF GET /index.htm H
DE AD BE EF DE AD BE EF DE AD BE EF DE AD BE EF TTP/1.1..Host:ww
