How to globally set the uri-encoding to UTF-8 in JBoss EAP ?

Issue

• Is there a way to globally set the URI encoding to UTF-8 so that special characters like Chinese or Japanese characters are printed properly.
• Is there any other way to set the URI_ENCODING property other than JBoss system property?
• How to enforce UTF-8 character encoding in a servlet?
• We are migrating one application from JBoss EAP 6.3 to 7.1.4 and after forcing the encode configuration using locale on the operating-system layer that is es_PE.utf8 that changes did not correct the issue.
