Uploading file - unicode file type gives error

Question

Hello,
I am trying to upload an xml file.
If the file is of ASCii format I can import this file ,but if the file format is changed to unicode or utf-16 I get sax parser error.
I noticed one thing though,ascii file seems to appear in this format
<?xml version="1.0" encoding="UTF-8"?>
<addresses>
<address>
<street-name>22 11th ave SW</street-name>
<city>Dynotopia</city>
</address>
</addresses>
Where as when I change the file format to unicode it appears like this
?< ? x m l v e r s i o n = " 1 . 0 " e n c o d i n g = " U T F - 8 " ? >
< a d d r e s s e s >
< a d d r e s s >
< s t r e e t - n a m e > 2 2 1 1 t h a v e S W < / s t r e e t - n a m e >
< c i t y > D y n o t o p i a < / c i t y >
< / a d d r e s s >
< / a d d r e s s e s >
?< ? x m l v e r s i o n = " 1 . 0 " e n c o d i n g = " U T F - 8 " ? >
< a d d r e s s e s >
< a d d r e s s >
< s t r e e t - n a m e > 2 2 1 1 t h a v e S W < / s t r e e t - n a m e >
< c i t y > D y n o t o p i a < / c i t y >
< / a d d r e s s >
< / a d d r e s s e s >
Can some one guide me to automate this process so that my sax processor automatically set itself to the appropriate file format?
or is it possible at all?

Thanks DrClap,
I read the article ( from the link u reffered).
Here is my problem,
I am uploading an xml file, here is the code
if(req.getContentLength() > 0) {
BufferedReader reader = req.getReader();
String line = reader.readLine();
if((line == null) || (line.indexOf(boundary) == -1)) {
//error generator
StringBuffer part = new StringBuffer();
while((line = reader.readLine()) != null) {
if(line.indexOf(boundary) == -1) {
part.append(line + "\n");
} else {
parts.add(part.toString());
part = new StringBuffer();
now my guess is when we convert an ASCii type to string above it works fine,but when the type is otherthen ASCii the conversion of file to string screws up...
can u pls guide me to make it work so it doesn't.
