[#3425] - jasperjpivot-5.1.0 bug OLAP view export to excel symbols in utf-8 encodding

If export to excel in OLAP view simbols from data base in utf-8 encodding, then this symbols shows incorrect.

In xsl file jasperreports-server-cp-5.5.0\apache-tomcat\webapps\jasperserver\WEB-INF\jpivot\table\xls_mdxtable.xsl encodding for export is set to utf-8:

...
<xsl:output method="html" indent="yes" encoding="utf-8"/>
...
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
...

I found source code of jasperjpivot lib only jasperjpivot-5.0.0-src version on sourceforge.net.
File jasperjpivot-5.0.0-src\jpivot\src\java\com\tonbeller\jpivot\print\PrintServlet.java is not content valid code for print xls output in utf-8 encodding.

Lib jasperjpivot-5.1.0 is content this bug too.

I can fix this bug, but I can't found sourses of jasperjpivot-5.1.0 version. How I can get this sourses?

I fix bug in 5.0.0 sourses and attach this file.
