JasperReports Integration PDF is created with ISO-8859-1 instead of UTF-8

Question

Hi,
This is a strange problem i'm struggling with. Since about one month the PDF's are created with the wrong character set. Instead of UTF-8 (this is also given as a parameter calling the procedure as you see below) the PDF are always created with ISO-8859-1.
declare
l_jasper_report_url VARCHAR2(100) DEFAULT 'http://localhost:8180/JasperReportsIntegration/report';
l_rep_name VARCHAR2(80) DEFAULT'SLRReports/SLR_Statistic_Service_Level_Report_Monat';
l_rep_format VARCHAR2(10) DEFAULT 'pdf';
l_data_source VARCHAR2(20) DEFAULT 'default';
l_rep_locale VARCHAR2(10) DEFAULT 'de_CH';
l_rep_encoding VARCHAR2(10) DEFAULT 'UTF-8';
l_StartDate DATE;
l_EndDate DATE;
l_MinDowntime INTEGER DEFAULT 1;
l_ServiceHour CHAR DEFAULT 'Y';
l_name VARCHAR2(50);
l_typ VARCHAR2(20) DEFAULT 'monatsreport_ccps';
l_additional_params VARCHAR2(200);
l_mime_type VARCHAR2(30);
l_blob BLOB;
BEGIN
l_StartDate := to_date('01.'||to_char( add_months(SYSDATE,-12),'MM.YYYY'),'DD.MM.YYYY');
l_EndDate := to_date('30.'||to_char( add_months(SYSDATE,-1),'MM.YYYY'),'DD.MM.YYYY');
l_name := 'slr-statistik-'||to_char(l_StartDate,'YYYY-MM')||'.pdf';
l_additional_params := 'UserName=SYSTEM'||chr(38)||'String_StartDate='||to_char(l_StartDate,'dd.mm.yyyy')||chr(38)||'String_EndDate='||to_char(l_EndDate,'dd.mm.yyyy')||chr(38)||'SLR_MinDowntime='||l_MinDowntime||chr(38)||'SLR_ServiceHour='||chr(38)||l_ServiceHour;
xlog ('PRC_GET_REPORT_TUNNEL', 'url (orig):' || l_rep_name||':'||l_additional_params);
-- generate the report and return in BLOB
xlib_jasperreports.set_report_url (l_jasper_report_url);
xlib_jasperreports.get_report (
p_rep_name => l_rep_name,
p_rep_format => l_rep_format,
p_data_source => l_data_source,
p_rep_locale => l_rep_locale,
p_rep_encoding => l_rep_encoding,
p_additional_params => l_additional_params,
p_out_blob => l_blob,
p_out_mime_type => l_mime_type );
dbms_output.put_line('p_out_mime_type: '||l_mime_type);
-- insert into report (id,name,typ,mime_type,lob_text,datum) values (p_report_seq.nextval,l_name,l_typ,l_mime_type,l_blob,sysdate);
-- commit;
-- apex_application.g_unrecoverable_error := TRUE;
EXCEPTION
WHEN OTHERS THEN
xlog ('PUT_BLB', SQLERRM, 'ERROR');
RAISE;
END;
It looks like the procedure UTL_HTTP.get_header ignores the encoding parameter and overwrites it with ISO-8859-1. I also tried to set it with UTL_HTTP.set_header before calling UTL_HTTP.get_header buth that didn't help either.
Then I started the JVM is started with the UTF-8 option and that made no change.
There were no new installation on Oracle, tomcat or JasperReports side. So I'm wondering what has caused this string behaviour.
Does anyone had this problem before or has a solution for it?
I appreciate your help very much.
Thanks and regards,
Chris

Hi,
As my understanding, you could choose the encoding ways by yourself:
Change your Internet Explorer 9 language
encoding settings
