问题
I have a Drools decision table in Excel, and some of the strings used in rules have "Á" characters. When I build rules package in Guvnor from this decision table, I get wrong characters in rules source.
For instance,
in spreadsheet -> Área de Lazer|POR,
in built drl file -> �rea de Lazer|POR
Is there any way Guvnor can be tuned to support UTF-8 in this case? Had anyone faced similar issue?
Thanks

Hi,
I have added following code to ExcelParser.java:
WorkbookSettings ws = new WorkbookSettings();
ws.setEncoding("UTF-8");
Workbook workbook = Workbook.getWorkbook( inStream , ws);
I have successfully built drools project from git-hub, but when I try building guvnor-webapp to test this, either with maven 2.2.1 or maven 3.0.3, I get the same error:

Any help on this would be appreciated!
Thank you!
P.S. I have read README document, and proceeded as described.

The issue is still open and not easy to fix because excel file encoding differs from locale to locale.
One known workaround (suggested by Amer Zec) is to start the app server on which Guvnor runs with -Djxl.encoding=cp1252 (if you're West-European, otherwise use another encoding than cp1252).
