Extra characters getting appended after decoding

Question

Hi All,
I am trying to decode the special characters by using the following function
public static String decode(String str) throws Exception
byte[] b0 = new byte[str.length()];
Pattern p = Pattern.compile(
"\\G(?:=(\\p{XDigit}{2})|[\\p{Graph}\\p{Blank}&&[^=]])");
Matcher m = p.matcher(str);
int idx = 0;
while (m.find())
b0[idx++] = m.start(1) != -1
? (byte)(Integer.parseInt(m.group(1), 16))
: (byte)m.group().charAt(0);
// byte[] b1 = Arrays.copyOf(b0, idx);
return new String(b0, "UTF-8");
But if i decode "=C2=A365=20sheetal " to £65 sheetal..,the decode is proper but it is adding extra characters like £65 sheetal?????? at the end .
How can i make my decode function not to add extra characters?OR HOW CAN I JUST SAVE "£65 sheetal " THIS VALUE??
THANKX

The problem got solved..,its decoding every extended bit values.
The function was changed little bit.Array copy is done using for loop.
public static String decode(String str) throws Exception
byte[] b0 = new byte[str.length()];
Pattern p = Pattern.compile(
"\\G(?:=(\\p{XDigit}{2})|[\\p{Graph}\\p{Blank}&&^=])");
Matcher m = p.matcher(str);
int idx = 0;
while (m.find())
b0[idx++] = m.start(1) != -1
? (byte)(Integer.parseInt(m.group(1), 16))
: (byte)m.group().charAt(0);
// byte[] b1 = Arrays.copyOf(b0, idx);
byte[] b1=new byte[idx];
for(int i=0;i<idx;i++){
b1=b0[i];
return new String(b1, "UTF-8");
Can any one say me,why euro symbol appears as ? in web-ui ,but it is saved in database as euro symbol itself?
Thankx
