TIBCO Business Studio

If you use TIBCO Business Studio, data sent from TIBCO Business Studio to iProcess Engine is converted to the encoding specified in the process attribute DEPLOY_XSL_OUT_ENCODING. Therefore you must:

Set the iProcess Engine process attribute DEPLOY_XSL_OUT_ENCODING to UTF-8 by using the SWDIR\util\swadm utility as follows:
swadm set_attribute 0 ALL 0 DEPLOY_XSL_OUT_ENCODING
   UTF-8

(The default is ISO-8859-1.)
