Japanese (non-ASCII) Character Issues in OAM headers variable

I have few user records with Japanese character (like 高山) in their attributes. Querying these users in OVD through ODSM displays it correctly . However, the same attributes when passed as OAM header variable through OAM-Authorization-Scheme spit out garbage like '=?UTF-8?B?6auY5bGx?=' .

This happens because the Webgate will encode any non-ASCII characters in header variables according to RFC 2047. It is the receiving OAM-protected application that will decode the encoded characters. The following java sample code will be a quick rescue. This will transform the non-ASCII character to a readable one.
:
import javax.mail.internet.MimeUtility ;
System.out.println("The Actual Value is := " + MimeUtility.decodeText("=?UTF-8?B?6auY5bGx?=")) ;
:

Your result will be =
The Actual Value is := 高山
