You're probably inadvertently interpreting the stream as UTF-8 instead
of straight-up bytes when you convert it to a String.  If you are using
a Reader, use new InputStreamReader(in, "ISO-8859-1") to make sure you
get a one to one mapping of byte values between 0 and 255 to Java
chars.  Otherwise your stream is going to be interpreted as multi-byte
characters and the data you store in your String will not be what you
intend.  It's a good thing you used [\\x00-\\xff]* instead of .*,
otherwise you wouldn't have caught the problem.
