Get Windows of information through SNMP, meet Chinese as hexadecimal, conversion or not, specific information is as follows:
Oid for Windows system time: 1.3.6.1.2.1.25.1.2.0=07: e3:09:0 b: 15:06:14:06
As above information through the following methods after the conversion is gibberish, including specified code: utf-8, GB2312, GBK, ISO - 8859-1 conversion is garbled,

Several attempts fail, the great god and see how to convert,

Public static String getChinese (String octetString) {//snmp4j in Chinese directly into hexadecimal String
Try {
String [] temps=octetString. Split (" : ");
Byte [] bs=new byte [temps. Length];
for (int i=0; i Bs [I]=(byte) Integer. ParseInt (temps [I], 16);

//GB2312 ISO - 8859-1 ASCII
Return a new String (bs, "GB2312");
} the catch (Exception e) {
e.printStackTrace();
return null;
}
}

}
Return a new String (bytes);
}

Looking forward to the great god to save, for many days, Chinese garbled question not to save.

Reason: the problem on the basis of SNMP4J string class OctetString,
