The spring message tag is not scaping html properly when spanish accent is present and htmlEscape attribute is set to true.
Text code (in property file):
$labelUnsubscribe = '<spring:message code="label.unsubscribe" htmlEscape="true" />';
Cancelar subscripci& oacute;n --> note the &Xcute not scaped.
'EncodingFilter' is set to UTF-8.
When the htmlEscape attribute is set to false or the property is not specified, the message is shown correctly, but we think that the output should be scaped correctly when the property is set to true, according with the documentation.
URL of the same issue reported by another user on stackoverflow is provided. In our case the issues occurs when the property is set to htmlEscape="true" in a explicit way.
