Header Encoding Problem

           Summary: Header Encoding Problem
           Product: Tomcat 4
           Version: 4.1.27
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Unknown
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: kenneth.y.kwan@pccw.com


Tomcat 4.1.2x seems always returned headers encoded in UTF8 irrespective of 
content type setting. This casued browser(MSIE) cannot download file with 
correct non-ISO characters filename. There is no such problem found in 4.0.6.

Have tried charset=Big5, ISO8859-1, ..., all failed.

Example:

// filename obtained from file system in ISO format and convert to correct big5 
encoding
filename=new String(filename.getBytes("ISO8859-1"), "big5");
response.setContentType("application/octet-stream;charset=xxx"); 
response.setHeader("Content-encoding","binary");
String resp=filename; // read from disk
response.setHeader("Content-Disposition", "filename="+resp);
ServletOutputStream out = response.getOutputStream();
// ... read the file from disk and write to user
out.close();
